Dental phobias and anxieties: evidence for conditioning processes in the acquisition and modulation of a learned fear

The present study investigated some of the factors which differentiate individuals with dental anxieties and phobias from those without such fears. In particular, two questions were addressed: (i) What differentiates subjects who have never been anxious about dental treatment from subjects who at some time have been anxious? and (ii) What factors lead to subjects changing their attitudes either from anxious to relaxed or from relaxed to anxious? The results suggest that the factors which influence the acquisition and modulation of dental anxieties are consistent with the associative and representational processes portrayed in contemporary models of human conditioning. Subjects who reported never having had anxieties about dental treatment were less likely to have had a painful dental treatment than subjects who did report an anxiety. Subjects who did report a painful dental experience but did not acquire anxiety reported a history of dental treatment favourable to the operation of latent inhibition. Subjects who reported that they were good at enduring pain were more likely to report a longer interval between their very first dental treatment and their first painful dental treatment. Under some conditions in which latent inhibition should have precluded the acquisition of a dental fear, an anxiety appeared to be acquired because a very painful experience had attenuated the latent inhibition process. Subjects whose dental anxiety did not remit reported significantly more painful and traumatic dental experiences than subjects whose anxiety did remit.     

Group and individual change in the treatment of drug addictions: a follow-up study in therapeutic communities

The pre-post treatment change of 112 patients in two therapeutics Spanish communities is described. The Addiction Severity Index (ASI) was used at intake and at the end of the treatment program. Results of the treatment program were evaluated by applying composite scores (CS) of the ASI, and the evolution of each patient was evaluated using the Reliable Change Index (RCI). 69.7% of the sample completed treatment, and 30.3% dropped out prematurely. At intake, the percentage of people who could improve in the different areas of the ASI ranged between 35.1% for alcohol consumption and 95.3% for family relationships. At the follow-up, the percentage of subjects who showed significant statistical improvements in the different areas varied between 7.9% in family relations and 66.7% in alcohol consumption. The percentage of patients who deteriorated was less than 10% for all variables. Implications for further research and clinical practice are commented upon.     

Source of improvement in balance control after a training program for ankle proprioception

Previous research on healthy individuals reported improvements in balance control following a purported ankle proprioception-training program. The training may have resulted in a general rather than a specific enhancement of ankle proprioception. To test this hypothesis, subjects were constrained at the hips and trunk with a custom-made thoracolumbosacral orthosis and performed a one-leg standing test with eyes closed and head tilted back, so that they had to rely primarily on their ankle musculature to keep their balance. Subjects were retested after training on the BAPS three times a week for 4 weeks, following the training recommendations of the manual. Subjects' bodies were not constrained during the training. Analysis showed that subjects made improvements during training in performing more difficult tasks on the board. On the one-leg test, however, there were no improvements in sway velocity, number of touchdowns, or falls relative to pretest scores. Improvements observed during training likely resulted from diffuse enhancement of proprioception in other body segments such as the knees, hips, spine, and upper extremities. A training program in control of general balance does not specifically target ankle proprioception.     

The influence of reward/punishment and personality pupil attainment

Hypotheses (inferred from Gray, 1970) were tested that under reward conditions, Extrovert (E)+ subjects will achieve better than E− subjects and Neurotic (N)+ subjects will achieve better than N− subjects, while under punishment conditions, E− subjects will achieve better than E+ subjects and N− subjects will achieve better than N+ subjects. Three secondary school classrooms were identified in which the teacher in mathematics was predominantly rewarding, offered a balance of reward and punishment or was predominantly punishing. The pupils in these classes were 82 boys in their 14th year. The Eysenck Personality Questionnaire: Junior Version was administered. Individual scores for E and N were ascertained. All boys were administered the Profile of Mathematical Skills: Level 2 (France, 1979). After 10, 20, 30, 40 and 50 school days, parallel arithmetic tests were administered. Inspection of the resulting graphs of mathematics progress indicated that the hypotheses were not confirmed, which made further statistical analysis inappropriate. However, issues arose in conducting the research that suggested improvements over an earlier study (McCord & Wakefield, 1981). Difficulties encountered in the present research are described and suggestions are made for improvements to future research in this area.     

Manifestations, acquisition and diagnostic categories of dental fear in a self-referred population

This study aimed to clarify how manifestations and acquisition relate to diagnostic categories of dental fear in a population of self-referred dental fear patients, since diagnostic criteria specifically related to dental fear have not been validated. DSM III-R diagnostic criteria for phobias were used to compare with four existing dental fear diagnostic categories, referred to as the Seattle system. Subjects were 208 persons with dental fear who were telephone interviewed, of whom a subsample of 155 responded to a mailed Dental Anxiety Scale (DAS), State-Trait Anxiety Inventory and a modified FSS-II Geer Fear Scale (GFS). Personal interviews and a Dental Beliefs Scale of perceived trust and social interaction with dentists were also used to evaluate a subsample of 80 patients selected by sex and high dental fear. Results showed that the majority of the 80 patients (66%), suffered from social embarrassment about their dental fear problem and their inability to do something about it. The largest cause of their fear (84%) was reported to be traumatic dental experiences, especially in childhood (70%). A minority of patients (16%) could not isolate traumatic experiences and had a history of general fearfulness or anxiety. Analysis of GFS data for the 155 subjects showed that fear of snakes and injuries were highest among women; heights and injections among men. Fear of blood was rarely reported. Spearman correlations between GFS individual items and DAS scores indicated functional independence between dental fear and common fears such as blood, injections and enclosures in most cases. Only in specific types of dental fear did these results support Rachman and Lopatka's contention that fears are thought to summate.(ABSTRACT TRUNCATED AT 250 WORDS)     

Preventing conduct problems, promoting social competence: a parent and teacher training partnership in head start

Studied the effectiveness of parent and teacher training as a selective prevention program for 272 Head Start mothers and their 4-year-old children and 61 Head Start teachers. Fourteen Head Start centers (34 classrooms) were randomly assigned to (a) an experimental condition in which parents, teachers, and family service workers participated in the prevention program (Incredible Years) or (b) a control condition consisting of the regular Head Start program. Assessments included teacher and parent reports of child behavior and independent observations at home and at school. Construct scores combining observational and report data were calculated for negative and positive parenting style, parent-teacher bonding, child conduct problems at home and at school, and teacher classroom management style. Following the 12-session weekly program, experimental mothers had significantly lower negative parenting and significantly higher positive parenting scores than control mothers. Parent-teacher bonding was significantly higher for experimental than for control mothers. Experimental children showed significantly fewer conduct problems at school than control children. Children of mothers who attended 6 or more intervention sessions showed significantly fewer conduct problems at home than control children. Children who were the "highest risk" at baseline (high rates of noncompliant and aggressive behavior) showed more clinically significant reductions in these behaviors than high-risk control children. After training, experimental teachers showed significantly better classroom management skills than control teachers. One year later the experimental effects were maintained for parents who attended more than 6 groups. The clinically significant reductions in behavior problems for the highest risk experimental children were also maintained. Implications of this prevention program as a strategy for reducing risk factors leading to delinquency by promoting social competence, school readiness, and reducing conduct problems are discussed.     

Relationships between locus of control,health value,and preventive health behaviors among women

This study examines the relationships between locus of control expectancies, rated health value, and reported participation in preventive health behaviors among a healthy sample of undergraduate women. The prediction that participation in preventive health behaviors would be a joint function of an internal health-related locus of control belief and holding health in high value was not supported. Instead, individuals who valued their health reported participating in a greater number of health-enhancing behaviors compared to those who valued their health less. Respondents' scores on a health value scale in combination with their rated health status proved to be better predictors of health behaviors than their locus of control beliefs. Limitations of locus of control research with young, healthy individuals are discussed and further investigation into the utility and validity of health value scales is recommended.     

Differences in risk factors and adjustment for male and female delinquents in treatment foster care

Differences by gender in the presence of risk factors, patterns of previous delinquency, and response to treatment were examined for a sample of 88 adolescents who were placed in Treatment Foster Care. Females were found to have fewer foster parent-reported problem behaviors than their male counterparts during the first month of treatment. By month 6, problem behavior levels for males had dropped, while scores for female subjects had increased to the level of males at month 1. No differences in pre-post arrest data or program completion rates for males and females were found. Implications for research on and treatment of female adolescents with conduct problems are discussed.     

Desired control and felt control as mediators of stress in a dental setting

Control-related variables have clearly affected stress responses in previous research (Thompson, 1981). Prior work, however, has primarily emphasized the amount of control that subjects perceive they have. In the three studies reported here, we examined the added predictive utility of assessing subjects' desire for control. Data from all three studies indicate that subjects who have a high desire for control coupled with a low feeling of control are characterized by particularly high degrees of dental distress. These results were found both in settings where patients anticipated immediate dental treatment and where treatment was not imminent. In addition, the results indicate that this "at risk" group reported greater distress before and immediately after actual dental treatment. Furthermore, they remembered their dental treatment as being more aversive 1 week after treatment. The practical implications and theoretical significance of these data are considered.     

Predicting cognitive recovery from closed head-injury in children and adolescents

Longitudinal data from 84 head-injured children and adolescents, who were tested at three points in the first year postinjury, were analyzed to determine the best combination of demographic, injury-related, and behavioral factors predicting cognitive performance. Dependent variables were language, memory, visuomotor, and speeded performance factor scores obtained through confirmatory factor analyses of an extensive test battery. Multiple regression analyses indicated that injury severity and the existence of previous psychological, physical, or cognitive disorders were primary for predicting acute (1 month post-hospital discharge) performance for older subjects. For younger subjects, however, parental marital status was the most important correlate of acute cognitive performance. Those residing in homes with both parents fared better than children in one-parent families. At 6 months and 1 year postinjury, the older subjects who performed most poorly initially remained the most impaired. For younger children, acute cognitive standing was also an important predictor of later performance, but parental marital status remained a crucial influence on their longer-term recovery of cognitive skills.     

Pathways of Risk and Resilience: Impact of a Family Resilience Program on Active‐Duty Military Parents

Over the past decade, studies into the impact of wartime deployment and related adversities on service members and their families have offered empirical support for systemic models of family functioning and a more nuanced understanding of the mechanisms by which stress and trauma reverberate across family and partner relationships. They have also advanced our understanding of the ways in which families may contribute to the resilience of children and parents contending with the stressors of serial deployments and parental physical and psychological injuries. This study is the latest in a series designed to further clarify the systemic functioning of military families and to explicate the role of resilient family processes in reducing symptoms of distress and poor adaptation among family members. Drawing upon the implementation of the Families Overcoming Under Stress (FOCUS) Family Resilience Program at 14 active‐duty military installations across the United States, structural equation modeling was conducted with data from 434 marine and navy active‐duty families who participated in the FOCUS program. The goal was to better understand the ways in which parental distress reverberates across military family systems and, through longitudinal path analytic modeling, determine the pathways of program impact on parental distress. The findings indicated significant cross‐influence of distress between the military and civilian parents within families, families with more distressed military parents were more likely to sustain participation in the program, and reductions in distress among both military and civilian parents were significantly mediated by improvements in resilient family processes. These results are consistent with family systemic and resilient models that support preventive interventions designed to enhance family resilient processes as an important part of comprehensive services for distressed military families.     

Pregenital fixation and perceptual distortions to conflict-laden material.

Three standard questionnaire measures of oral and anal fixation were administered to 142 students. On the basis of their scores 26 students were selected and shown tachistoscopic exposures of pictures designed to activate oral or anal conflicts. Five subjects in each group had extremely high scores on the corresponding measure of fixation, five had extremely low scores, and 16 had intermediate scores. It was hypothesised that individuals who were fixated at one or other of the psychosexual stages would show stereotyped perceptual distortions to repeated dim exposures of the corresponding picture. Highly fixated subjects showed significantly more deviant responses than did subjects who showed low levels of fixation at the same stage. A form of Q-factor analysis indicated that subjects who were fixated at the oral sadistic or anal stages showed different patterns of perceptual distortions to the anal picture than those who were not fixated. These results were interpreted as supporting the link between defenses against anal eroticism and the anal character.     

The Short-Term Memory of Profoundly Deaf People for Words,Signs, and Abstract Spatial Stimuli

The short-term memory (STM) of 25 deaf and 20 hearing adults fluent in Australian Sign Language (Auslan) was tested using both free- and serial-recall versions of three tasks. On two tasks, where stimuli were presented as either written words or Auslan signs, hearing subjects performed significantly better than deaf subjects. This difference was attributed to the facility of the hearing subjects in translating these two classes of language-based stimuli into phonological codes, which have a preferred status in STM. On the third, language-free task, which was an adaptation of the Corsi Blocks test, the deaf and hearing subjects performed at comparable levels, indicating that differences in their STM became evident only with the introduction of language-based factors. Analyses restricted to the deaf subjects showed that performances on the language-based STM tasks correlated positively with scores on a reading comprehension test. Also, deaf subjects who reported an oral education outperformed their counterparts, who reported a total communication (oral plus signed English) education on the language-based STM tasks. Thus, for this diverse adult deaf sample, proficiency in STM for language-based material, skill in reading, and report of an oral rather than total communication education appear to covary.     

Effects of program‐advertisement congruity and advertisement emotional appeal on memory for health and safety advertisements

The aim of this study was to examine the memory for health and safety advertisements (HSAs) embedded within a congruent (documentary) or incongruent (sitcom) program. A total of 80 participants aged 16–25 years took part. Participants watched either a sitcom or a health‐related program with health and safety and “filler” advertisements. After they watched the 30 minute program, they were given free and cued recall measures as well as program evaluation. These showed that the free recall scores were generally better for HSAs than filler advertisements across both program types, while the cued recall and advertisement recognition scores were better for filler advertisements than HSAs. Memory scores revealed that the HSAs were better remembered than filler advertisements in an incongruent program environment. Health advertisements are better recalled in non‐health‐related programs. This supported the interference hypothesis.     

EFFECTS OF ACHIEVEMENT MOTIVES AND SEX ON WRESTLING ABILITY AND MOTOR PERFORMANCE

An earlier study of main effects of achievement motives on performance amongst boy wrestlers was repeated with girls. The 1970 Achievement Motives Scale of Gjesme and Nygård was administered to 29 girls, and subjects' scores were sampled for three different wrestling championships at a national level. Oxygen uptake, speed of movement, four muscular strength exercises, and serial performance of five wrestling holds were measured. As with males, success-oriented females performed better than indifferent-oriented subjects in wrestling championships. The former group performed also better than the latter in pull-ups, sit-ups, forward throw and 1/4 Nelson. In addition, success-oriented females performed better than those who were failure-oriented in pull-ups and sit-ups, although this was not the case in other tasks and championships. Indications of sex differences in the relationship between motivation and performance were found among subjects who aim for achievement and, at the same time, have a high motive for failure, i.e. those who were conflict-oriented. Motive patterns and sex influence some, but not all, of the responses measured in the different tasks. Suggestions for future systematic research on a task effect are discussed. In general, the data indicate that, among highly selected and high ability boys and girls who set a high value on goals of an activity, relationships between achievement motives and performance in that activity should emerge for both sexes. In addition, sex should modify motive-performance relationships.     

Wire-bending test as a predictor of preclinical performance by dental students

Traditional Dental Aptitude Test and academic grade point average have been shown to be poor predictors of clinical performance by dental students. To refine predictors of psychomotor skills, a wire-bending test was given to 105 freshmen at the beginning of their dental education. Grades from seven restorative preclinical courses in their freshman and sophomore years were compared to scores on wire bending and the three traditional predictors: GPA, academic aptitude, and perceptual aptitude scores. Wire-bending scores correlated significantly with six out of seven preclinical restorative courses. The predictive power for preclinical performance was doubled when wire bending was added to traditional predictors in stepwise multiple regression analysis. Wire-bending scores identified students of low performance. These preliminary results suggest that the wire-bending test shows some potential as a screening test for identifying students who may hae psychomotor difficulties, early in their dental education.     

Individualized behavior therapy for alcoholics: a third year independent double-blind follow-up.

An independently conducted double-blind study providing third year follow-up data for 53 of 70 male alcoholics who served as subjects in an experiment evaluating “Individualized Behavior Therapy (IBT)” techniques is reported. In the original study, subjects were initially assigned to either a controlled drinking or non-drinking (abstinence) treatment goal, and were then randomly assigned to either an experimental group receiving IBT or a control group receiving conventional state hospital treatment oriented towards abstinence. Previously reported results showed that IBT subjects functioned significantly better than control subjects throughout the first year of follow-up. Second year follow-up results found that IBT subjects treated with a controlled drinking goal functioned significantly better than their respective control subjects on a variety of measures, including drinking behavior. Differences between IBT subjects treated with a non-drinking goal and their control subjects did not retain statistical significance during the second year of follow-up. The independently determined follow-up data showed that during the third post-treatment year, subjects in the experimental groups generally functioned better than their respective control subjects. Comparison of the controlled drinking experimental group with its control group showed the significantly better functioning of subjects in the experimental condition on a number of drinking and other life functioning measures. Comparison of the non-drinking groups indicated only one possible difference on the drinking related measures involving a trend for subjects in the experimental condition to abstain more than those in the non-drinker control group. On other life functioning measures, however, subjects in the non-drinking experimental condition showed consistent improvement over their respective control subjects. Both of the controlled drinking groups reported more controlled drinking days than the non-drinking groups throughout the third year follow-up period.     

Perceived sources and levels of stress,general self-efficacy and coping strategies in clinical dental students

The aims of this study were to identify sources of stress among clinical students and to evaluate the students’ perceived levels of stress, general self-efficacy and effective coping strategies in a private dental school environment. The study group consisted of 130 undergraduate clinical dental students in a Turkish private dental school, during the academic year 2014–2015. The students were surveyed using modified version of the dental environment stress (DES) survey, the perceived stress scale, the general self-efficacy scale (G-SES) and the brief coping scale. Age, sex, year of study, history of psychiatric treatment and factors that affected the choice of dentistry were also recorded. Final year and female clinical dental students, who were found to be the most stressful students, had moderate to high perceived stress scores. Total and ‘Faculty and administration’ related DES scores increased with the year of study. Stressors related to ‘Workload’ and ‘Clinical training’ affected females more than males. G-SES scores were higher in male students and students, who had no history of psychiatric treatment. The most and the least common coping strategies were ‘Planning’ and ‘Substance abuse’, respectively. ‘Religion’ was found to be one of the main coping strategies. Stress factors affecting Turkish clinical dental students studying at private dental school differed from the previously reported stress factors affecting students studying at a governmental dental school. Advanced year and female students experienced more stress than the other students.     

Two strategies in fricative discrimination

Synthetic noises from a [∫]-[s] continuum, followed by vocalic portions that influenced the location of the [∫]-[s] boundary in an identification test, were presented in AXB and fixed-standard AX discrimination tasks. The majority of naive subjects perceived these fricative-vowel syllables fairly categorically in both tasks; that is, discrimination functions followed the patterns predicted from identification scores and showed shifts contingent on the nature of the vocalic portion. However, two subjects achieved much better discrimination scores than the rest, and so did three experienced listeners and a group of less experienced subjects who had received some discrimination training in the AX task. These listeners, who (judging from their higher accuracy, pattern of responses, and subjective reports) successfully followed the nonphonetic strategy of restricting attention to the spectral properties of the fricative noise, were not influenced by different vocalic contexts. These results support the hypothesis that influences of vocalic context on fricative identification are tied to a phonetic mode of perception.
