Adherence to substance abuse treatment: clinical utility of two MMPI-2 scales.

In this study, we examined the ability of the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Addiction Acknowledgment scale (AAS; Weed, Butcher, McKenna, & Ben-Porath, 1992) and Negative Treatment Indicators scale (TRT; Butcher, Graham, Williams, & Ben-Porath, 1990) to predict adherence to and outcomes from substance abuse treatment. There was no evidence that the AAS was related to treatment adherence or outcome in our sample. However, results did reveal a significant positive relation between scores on the TRT scale and readmission to the hospital. Further analyses identified an optimal score for use in similar clinical populations and settings, and characteristics of high and low scorers. Compared to low scorers, high TRT scorers were more likely to not return for treatment after an initial screening interview. If they did return for treatment, high TRT scorers were more likely to experience fewer treatment days and to be rated as having lower motivation, poorer participation, and poorer comprehension of program materials. These findings provide promising initial evidence of the utility of the TRT scale for identifying patients who may be at a high risk for unsuccessful substance abuse treatment.     

Psychoticism and signalled versus unsignalled reaction time

Considering the findings that schizophrenics have been found to show relatively slow reaction times (RTs), and often do not benefit from ordinarily helpful information (e.g. a warning signal), the present study investigated the relationship between these variables and psychoticism (P). One hundred and three male Ss were administered a questionnaire which provides a measure of P. In addition, all Ss were tested on an RT task under unsignalled (i.e. no warning signal) and signalled conditions. The results showed that the expected improvement in reaction speed with a warning signal was of a lesser magnitude for those high on P. Furthermore, the difference was due to the faster RTs for high P scorers in the unsignalled condition. The data suggest that high P scorers are like schizophrenics in that they show less benefit from a warning signal, but are dissimilar in terms of reaction speed in an unsignalled task.     

Behaviour–emotional characteristics of primary‐school children rated as having language problems

Background Primary‐school teachers are expected to detect problems related to language function, but the teachers' evaluations may be heavily influenced by gender and classroom behaviour. Aim To investigate the relationship between language problems (LPs) and behaviour–emotional problems as rated by primary‐school teachers. Methods All participants participated in a population‐based study, the Bergen Child Study (BCS). Teachers of 9,072 children and parents of 6,234 children completed forms containing questions pertaining to language function and the strengths and difficulties questionnaire (SDQ) to screen for behaviour–emotional problems. LP was defined as a score above the 95th percentile on the sum score of five language items. Children achieving a total SDQ score above the 90th percentile were defined as high scorers, indicating a high risk for behavioural–emotional problems. Results Based on teacher reports, 540 children were defined as having LP, more boys (N = 366) than girls. Children defined as having LP were reported to have significantly higher scores on all SDQ subscales, and a higher total difficulty score than children without language problems (NLP). More LP boys than LP girls were defined as high scorers on the SDQ, with the highest effect size on the hyperactivity–inattention subscore. The agreement between teachers and parents was moderate to low, with the highest consensus of behaviour–emotional problems in children with LP. Conclusions Primary‐school children defined as having LP according to their teachers are frequently characterized by behavioural–emotional problems. Further assessment is warranted for primary‐school children defined as having LP by their teachers.     

Psychoticism and attentional flexibility

In three separate experiments, we tested the hypothesis that a systematic relationship between psychoticism (P) and visual selective attention is infrequently observed because the tasks typically used to test individual differences in efficiency of attentional mechanisms do not entail attentional flexibility. We manipulated the selection rule of the computerized divided visual attention (DIVA) task to be either (a) a predictable, or (b) a random manner, and a secondary task was added to check the quality of high P scorers’ performance in an interference condition; and we also introduced breaks between DIVA tasks to allow for cue utilization. Results revealed that low P scorers outperformed high P scorers in the regular selection rule alternation condition (cue utilization possible), whereas high P scorers performed better in random alternation condition – high P scorers also showed performance superiority in the dual task condition unless stimuli presentation was speeded up. Thus, P does not necessarily impair attentional performance; indeed, our data point to performance advantages of high P, especially attentional efficiency in tasks requiring small demands of attentional control.     

The influence of alexithymia and music on the incidental memory for emotion words

Alexithymia is a multifaceted personality construct which encompasses difficulties in identifying and expressing feelings along with an externally oriented cognitive style. We investigated whether congruent vs. incongruent emotional musical priming (happy and angry music) during encoding would moderate the effects of alexithymia on recognition rates. We found that high alexithymia scorers recognized fewer joy and anger words than low scorers. Angry music decreased recognition rates in high alexithymia scorers compared to low alexithymia scorers. The congruency and incongruency effects between music and words depended on alexithymia level. The anger deficit in high alexithymia scorers and the possible support provided by happiness cues are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Impulsivity/sociability and reinforcement in verbal operant conditioning

The present investigation was designed to study the relationship between impulsivity/sociability and modes of reinforcement in verbal operant conditioning. Two 2x3 randomized block designs, one each for impulsivity and sociability, were replicated ten times. One hundred and twenty undergraduate female students (60 for impulsivity and 60 for sociability) were individually subjected to Taffel's verbal conditioning procedure. When the conditioning scores of high and low scorers on the impulsivity and sociability scales were compared, it was found that under rewarding conditions ('good' and 'buzzer' in respect of sociability and 'good' in respect of impulsivity) the high scorers' score and under punishing conditions ('electric shock') the low scorers' score was the higher of the two. The study also revealed that the high scorers (on the impulsivity scale) conditioned more under rewarding conditions while the low scorers (both on the impulsivity and sociability scales) conditioned more under punishing ones.     

Psychoticism and sexual arousal to rape depictions

This study tested the hypothesis that high scorers on the Eysencks' P scale would become more sexually aroused by erotic material of a violent nature than low scorers. One hundred and forty-five college Ss were exposed to erotic auditory messages varying in degree of violence and pain experienced by the victim. Personality was assessed by a median split on the Eysencks' P scale. Sexual arousal was assessed by mercury strain gauge and self-report. Results, as predicted, showed a significant interaction between psychoticism and level of violence (rape vs nonrape): high P scorers showing greater sexual arousal (by both self-report and physiological assessment) to rape as compared to nonrape depictions whereas the opposite pattern occurred for low P scorers.     

Psychoticism and attentional flexibility

In three separate experiments, we tested the hypothesis that a systematic relationship between psychoticism (P) and visual selective attention is infrequently observed because the tasks typically used to test individual differences in efficiency of attentional mechanisms do not entail attentional flexibility.

Results revealed that low P scorers outperformed high P scorers in the regular selection rule alternation condition (cue utilization possible), whereas high P scorers performed better in random alternation condition – high P scorers also showed performance superiority in the dual task condition unless stimuli presentation was speeded up.

Relationships between Protestant Work Ethic and Work Effort in a Field Setting

Soixante-huit étudiants ont relevé leurs activatés quotidiennes pendant sept journées consécutives. Ils ont ensuite passé l'échclle de Mirels et Garrett, le "Protestant Work Ethic" datant de 1971 (P.W.E.). Les sujets qui présentent un score élevé au P.W.E. consacrent plus de temps a leurs etudes et moins à leurs loisirs (par comparaison avec ceux dont le résultat au P.W.E. est faible). Ces différences existent pour les jours ouvrés, mais pas pour le week-end.
Sixty-eight student subjects recorded their daily activities for seven consecutive days, and afterwards completed Mirels and Garrett's (1971) Protestant work ethic (PWE) scale. Compared to low PWE scorers, high PWE scorers worked longer hours on their study and spent less time on leisure. These differences occurred during weekdays but not at the weekend.     

SACRAL: toward the meaning and measurement of friendliness

Friendliness was regarded as a construct or dispositional tendency consisting of four components: Self-concept (S), the person's beliefs about self related to peer relationships; Accessibility (AC), giving behaviors involving attention and respect; Rewardingness (R), the giving of more tangible rewards, such as money and compliments; and Alienation (AL), personal beliefs about acceptance and the world as a friendly place. A 40-item questionnaire was developed to assess these components of friendliness. Studies of the questionnaire with college students and children supported its internal consistency, test-retest reliability, concurrent validity, construct validity, and discriminant validity. Although virtually all respondents reported themselves as friendly, high SACRAL scorers, when compared with low scorers, less frequently experience loneliness and in a variety of contexts claim to be more apt to engage in friendly behaviors. The impression that emerges of relatively low scorers on SACRAL is of people whose professed actions are somewhat inconsistent with their personal beliefs.     

Effect of schizotypy on responding maintained by free-operant schedules of reinforcement

Deviations from otherwise reliable patterns of responding in human performance on schedules of reinforcement could be associated with personality characteristics, such as psychometrically-measured schizotypy. The present study examined differences between high and low scorers on four schizotypy subscales (unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive non-conformity) on a random-ratio (RR) and random-interval (RI) schedule of reinforcement. Results showed a higher rate of responding on the RR than RI schedule, consistent with the differences in performance normally observed between these schedules. However, these differences were dependant on whether or not participants scored high or low on the schizotypy subscales, as well as the specific schedule parameters between the schedules. Specifically, high scorers on the unusual experiences (UE) subscale of the O-LIFE(B) were the only group in Experiment 1 not to show a difference in schedule performance, suggesting high scores on this subscale are linked to altered RR and RI performance. Experiment 2 explored this finding further using different schedule parameters, and confirmed that high scorers in UE did not differ in response rates between the two schedules.     

Personal ideals and socially desirable responding

The effect of personal ideals on socially desirable responding (impression management or IM, and self-deception or SDE) was examined in a study of 428 undergraduate students. The subjects indicated their endorsement of 56 values and filled in Paulhus's (1991) Balanced Inventory of Desirable Responding. Three IM types, viz. ingratiators, exemplificators, and intimidators, were defined from the subjects’ personal ideals. We hypothesized that both ingratiators and exemplificators score high and that intimidators score low on IM items. These hypotheses were confirmed, but the result for intimidators was only marginally reliable. Furthermore, it turned out that high IM scorers strove for collective values but high SDE scorers strove for individual values. The results are discussed as an expression of a self-construction process, which is based on personal, rather than social, ideals. In addition, the implications of the results for controlling the effect of socially desirable responding are discussed.     

Gaze and arrow cueing of attention reveals individual differences along the autism spectrum as a function of target context

Observing averted gaze results in a reflexive shift of attention to the gazed‐at location. In two experiments, participants scoring high and low on the Autism‐Spectrum Quotient questionnaire (AQ; Baron‐Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001 ) observed arrow and gaze cues to investigate cueing effect magnitude as a function of the context in which peripheral targets could appear. While identical cueing effects were found with gaze and arrow cues, the more striking results concerned target stimuli. In Experiment 1, targets could appear on a peripheral face, or on scrambled face parts. Overall, greater cueing effects were found when the target appeared on a face. However, this face bias was only observed in participants with low AQ scores, whereas high AQ scorers oriented more to scrambled features. Experiment 2 found equal cueing to targets appearing on tools, as compared with tool parts. However, individual differences were again observed, where low AQ scorers showed larger cueing towards tools, while high scorers oriented more to scrambled parts, as in Experiment 1. These results support the idea that low AQ individuals orient strongly to objects attended by others. However, since the same results were found for arrow cues, this effect may generalize to all central cues to attention. High AQ scorers possessing many more autistic‐like traits tended to orient more to scrambled shapes, perhaps reflecting a bias for orienting to local details.     

Cognitive therapy versus interoceptive exposure as treatment of panic disorder without agoraphobia

Cognitive therapy (CT) and interoceptive exposure (IE) as treatments of panic disorder without agoraphobia were compared in a sample of 69 patients, randomly allocated to condition. There were no significant differences between treatments as to reductions in panic frequency, daily anxiety levels and a composite questionnaire score, at posttest after the 12-session treatment, and at both follow-ups (4 weeks, 6 months). In both conditions, high percentages of patients were panic free at post and follow-up tests (range 75-92%). Although the reduction in idiosyncratic beliefs about the catastrophic nature of bodily sensations was equally strong in both conditions, post-treatment beliefs correlated strongly with symptoms at post and follow-up tests in the CT condition, but not in the IE condition. Reduction of beliefs may be essential in CT, but not in IE. This suggests that the two treatments utilize different change mechanisms.     

Protective factors and behavioral adjustment in preschool children of Iranian Martyrs

Out of 228 Iranian preschool Martyrs' children whose behaviour adjustment in the nursery settings was screened using the Preschool Behaviour Checklist, 12 well adjusted, zero scorers were compared with 8 poorly adjusted, high scorers. Using the parent's Behaviour Checklist, high scorers showed significantly more problems at home than zero scorers. On the Malaise Inventory, mothers of high scorers showed poorer mental health than mothers of zero scorers. Home observations showed that mother-child interaction was more aversive in high scorers than in zero scorers. More mothers of zero scorers had remarried.     

The relationship between creativity and psychosis-proneness

One-hundred and fifteen undergraduates were repeatedly administered a battery measuring schizotypal personality type and creativity (remote associations). Principal Components Analysis found a two-factor model to be most parsimonious. The pattern of results suggests that magical ideation and perceptual aberration items are represented by one factor and suspiciousness by the second. Analysis of consistent versus inconsistent high scorers on the schizoptypia measure indicated that inconsistent high scorers on the suspiciousness factor scored significantly higher than consistent high scorers on the creativity measure.     

General Newsletter

Low scores often have been ignored in validity research on the MMPI, yet these statistically significant deviations from the norm may be valuable sources of information and occur frequently enough to merit further investigation. The meaning of low scores on the MMPI-2 was examined for 822 male-female partner pairs in the MMPI-2 restandardization sample. Subjects were divided by MMPI-2 scale scores into high-, medium-, and low-score groups. Analyses of variance were performed with score level as the independent variable and partner ratings as dependent variables. Significant differences were found between the low- and medium-score groups with low scorers rated as better adjusted than medium scorers. More significant differences were found between the high-score and medium-score groups than between the low-score and medium-score groups; this suggested that high scores on MMPI-2 clinical scales are associated with poorer adjustment.     

Highs Are to Lows as Experts Are to Novices: Individual Differences in the Representation and Solution of Standardized Figural Analogies

Two experiments compared the strategies used by high and lower scorers on standardized figural analogy tests to represent and solve problems. In Experiment 1, subjects freely sorted completed analogy (A:a::B:b) problems into categories. High scorers categorized problems largely on the basis of well-constrained spatial transformations between problem terms; Low scorers sorted according to perceptual (i.e., shape) similarities among the figures constituting the problems. Experiment 2 compared the two groups' solution strategies in terms of specific patterns of eye movements used in viewing problem and answer terms. High scorers appeared to view problem terms in a more efficient fashion than did lower scorers. The lower scorers focused on noncritical figural relations (mapping figure A onto figure B), and they devoted more resources to processing the answer alternatives than did the high scorers. The pattern of results supports the view that high scorers tend to work in a more forward, or constructive, fashion, whereas lower scorers more often work backwards, using a response-elimination approach. Taken together, these findings converge to suggest specific aptitude-related differences in the representation and solution of standardized figural analogy problems. These differences bear some similarities to expert-novice differences in a number of other problem-solving domains.     

Dissociational body experiences: Differences between respondents with and without prior out‐of‐body‐experiences

Many people report having had an experience in which they felt as if their phenomenal self was separated in Cartesian space from their physical body. This phenomenon is often referred to as an ‘out‐of‐body’ (OBE) experience. Prior work has found OBE experients to score higher on measures of dissociation and to differ in regards to the perceptual experience of their body. Based upon this work, we theorized that the daily bodily experiences of people with and without a prior OBE would differ along a number of dimensions. In order to test this theory a questionnaire study was conducted. Of 243 respondents, 62 reported at least one prior OBE. Six scales on different aspects of bodily experience were administered. Respondents reporting a previous OBE were found to score significantly higher on measures of somatoform dissociation, self‐consciousness, body dissatisfaction, and lower on a measure of confidence in their physical self‐presentation than respondents without a previous OBE. The findings are discussed as supporting a dissociational theory of the OBE.
