Analysis and treatment of finger sucking

We analyzed and treated the finger sucking of 2 developmentally typical children aged 7 and 10 years. The functional analysis revealed that the finger sucking of both children was exhibited primarily during alone conditions, suggesting that the behavior was maintained by automatic reinforcement. An extended analysis provided support for this hypothesis and demonstrated that attenuation of stimulation produced by the finger sucking resulted in behavior reductions for both children. Treatment consisted of having each child wear a glove on the relevant hand during periods when he or she was alone. Use of the glove produced zero levels of finger sucking for 1 participant, whereas only moderate reductions were obtained for the other. Subsequently, an awareness enhancement device was used that produced an immediate reduction in finger sucking.     

"Transitional objects" as establishing operations for thumb sucking: a case study

This study examines the effects of a "transitional object" (surgical cloth) on the thumb sucking of a 3-year-old boy in two conditions: while sitting in the lap of his physical therapist and while alone in his crib. Sucking occurred when the cloth was present and did not occur when it was absent, regardless of condition. These results are discussed in terms of establishing operations, object attachment, and application.     

An Evaluation of a Self-Protection Skills Program for the Mildly Handicapped

The purpose of the present investigation was to determine the effects of a self-protection curriculum with a group of 10 junior high special education students. The curriculum (Ryerson & Sunden, 1981) was designed to increase the student's ability to identify strangers, recognize unsafe situations, use refusal skill, and understand acceptable and unacceptable touch. The effects of the curriculum were examined using a multiple baseline pre-posttest design across subjects. The results indicated a significant improvement in self-protection skills. Post testing data indicated the self-protection skills ere maintained over time.     

Validation of the Portuguese emotion awareness questionnaire for children and adolescents

This study examined the construct and concurrent validity of the Portuguese version of the Emotion Awareness Questionnaire (EAQ) in 302 children and adolescents (mean age 13 years old). The EAQ is a self-report questionnaire that allows for analysis of how youth experience and understand their own and others’ emotions. Participants completed the EAQ along with questionnaires for Worry and Somatic Complaints. Results confirmed the expected six-factor structure, good psychometric properties, and good concurrent validity. The EAQ is a reliable questionnaire, suitable for examining emotion awareness in Portugal.     

An evaluation of response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement

In the current study, we examined the utility of a procedure consisting of noncontingent reinforcement with and without response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement. Results are discussed in terms of examining the variables that contribute to the effectiveness of response cost as treatment for problem behavior maintained by automatic reinforcement.     

An integrated model for guiding the selection of treatment components for problem behavior maintained by automatic reinforcement

We evaluated the usefulness of 2 assessments to guide treatment selection for individuals whose prior functional analysis indicated that automatic reinforcement maintained their problem behavior. In the 1st assessment, we compared levels of problem behavior during a noncontingent play condition and an alone or ignore condition. In the 2nd, we assessed participants’ relative preferences for automatic reinforcement and social reinforcers in a concurrent‐operants arrangement. We used the results of these 2 assessments to assign 5 participants to a treatment based on noncontingent access to social reinforcers or to a treatment based on differential access to social reinforcers. We conducted monthly probes with the participants over 10 to 12 months to evaluate the effects of the treatment procedures. All participants showed reductions in problem behavior over this period.     

Varying response effort in the treatment of pica maintained by automatic reinforcement

Pica is a life-threatening behavior displayed by many individuals with developmental disabilities. In the current study, automatic reinforcement maintained the pica of 3 participants. Following functional analyses of pica, response-effort manipulations were conducted in which the effort to obtain pica or alternative items was varied systematically. Several general relations emerged as a result of the study. First, levels of pica were reduced relative to baseline when alternative items were available independent of the effort required to obtain alternative items or pica. Second, increasing the effort for alternative items resulted in increases in pica relative to when effort for alternative items was low. Third, increasing response effort for pica produced reductions in pica relative to baseline when alternative items were unavailable. Fourth, the highest levels of pica occurred when the effort to engage in pica was low or medium and no alternative items were available. These findings are discussed in terms of the relative effects of quality of reinforcement and response effort on behavior.     

Preference for unreliable reinforcement in children with mental retardation: the role of conditioned reinforcement

We examined the effects of conditioned reinforcement on children's choice between reliable (100%) and unreliable (50%) reinforcement under various stimulus conditions in a concurrent-chains procedure. The study was conducted across three experiments. Experiments 1 and 2 were conducted under conditions similar to basic laboratory work and consisted of participants selecting from one of two black boxes (placed on a table) that were correlated with different reinforcement schedules. In Experiment 3, we assessed a participant's preference for unreliable reinforcement during conditions in which the target responses were aggression and mands. Results of the three experiments showed that the participants preferred unreliable reinforcement under certain conditions. Findings are discussed regarding the role of specific stimuli (i.e., items correlated with a reinforcement schedule, adult reactions) as conditioned reinforcers and how they may influence children's preference for a response (e.g., aggression, self-injury) that produces reinforcement on a leaner schedule than a socially desirable response (e.g., mands).     

The relationship between emotion awareness and somatic complaints in children and adolescents: Investigating the mediating role of anxiety and depression

The objective of this study was to examine if emotion awareness in children and adolescents (age 7–18 years old) is directly related to somatic complaints, and if this relationship holds when considering symptoms of anxiety and depression as mediating factors. A number of questionnaires measuring emotion awareness, symptoms of anxiety and depression and somatic complaints were administered to Dutch schoolchildren (N?=?617). A path model was constructed, with the use of structural equation modelling. The results showed that two aspects of emotion awareness (bodily awareness and differentiating between emotions) contributed to the prediction of somatic complaints. However, this was no longer the case when controlling for symptoms of anxiety and depression. Thus, in this study, no direct relation was found between emotion awareness and somatic complaints. Instead, the relation was perfectly mediated by symptoms of anxiety and depression. The results suggest that focusing only on the relation between emotion awareness and somatic complaints is an oversimplified perspective that falls short as a starting point to find therapeutic solutions for children who suffer from somatic complaints.     

Response competition and stimulus preference in the treatment of automatically reinforced behavior: a comparison

Clinicians are particularly challenged by the development of interventions for behavior maintained by automatic reinforcement because reinforcers that maintain the responses often cannot be directly observed or manipulated. Researchers have conducted either preference assessments or competing items assessments when developing effective treatments for behavior maintained by automatic reinforcement. However, interventions based on these assessments have not been directly compared. The current study evaluated procedures to make such a comparison. High-competition items resulted in greater reductions in vocal stereotypy than did high-preference items for a preschool boy with autism.     

Effects of methylphenidate on sensitivity to reinforcement in children diagnosed with attention deficit hyperactivity disorder: an application of the matching law

The behavior of children diagnosed with attention deficit hyperactivity disorder (ADHD) has been hypothesized to be the result of decreased sensitivity to consequences compared to typical children. The present study examined sensitivity to reinforcement in 2 boys diagnosed with ADHD using the matching law to provide more precise and quantitative measurement of this construct. This experiment also evaluated the effects of methylphenidate (MPH) on sensitivity to reinforcement of children with ADHD. Subjects completed math problems to earn tokens under four different variable-interval (VI) schedules of reinforcement presented in random order under both medicated and nonmedicated conditions. Results showed that, in the medicated condition, the matching functions for both subjects resulted in higher asymptotic values, indicating an overall elevation of behavior rate under these conditions. The variance accounted for by the matching law was also higher under the medicated conditions, suggesting that their behavior more closely tracked the changing rates of reinforcement while taking MPH compared to placebo. Under medicated conditions, the reinforcing efficacy of response-contingent tokens decreased. Results are discussed with respect to quantifying behavioral changes and the extent to which the drug interacts with prevailing contingencies (i.e., schedule values) to influence behavioral variability.     

Sequenced neurocognitive and behavioral parent training for the treatment of ADHD in school-age children

The present study examines the potential of sequencing a neurocognitive intervention with behavioral parent training (BPT) to improve executive functions (EFs), psychiatric symptoms, and multiple indices of functional impairment in school-age children aged 7 to 11 years who have been diagnosed with attention-deficit/hyperactivity disorder (ADHD). Specifically, in a randomized controlled trial design, 85 children were assigned to either Cogmed Working Memory Training (CWMT) followed by an empirically supported, manualized BPT intervention, or to a placebo version of CWMT followed by the same BPT intervention. Working memory maintenance (i.e., attention control/short-term memory), working memory processing and manipulation, ADHD and oppositional defiant disorder (ODD) symptoms, impairment in parent–child dynamics, familial impairment, and overall functional compromise were evaluated as outcomes. The results suggest specific effects of the combined CWMT and BPT program on verbal and nonverbal working memory storage and nonverbal working memory processing and manipulation but no incremental benefits in regard to ADHD symptoms, ODD symptoms, and functional outcomes. The present findings do not support the hypothesis regarding the complementary and augmentative benefits of sequenced neurocognitive and BPT interventions for the treatment of ADHD. These results, the study’s limitations, and future directions for research are further discussed.     

Effectiveness of an empirically supported treatment for social phobia in the field

This study examined the effectiveness of individual exposure combined with cognitive restructuring for social phobia in a clinical setting as well as the influence of sample restriction criteria on the effect size. Participants were 217 unselected patients with a primary diagnosis of social phobia who were treated by 57 therapists in four outpatient clinics of the Christoph-Dornier-Foundation of Clinical Psychology in Germany. Results 6 weeks after the end of therapy showed highly significant reductions in social phobic fears and avoidance as well as in general anxiety and symptoms of depression. However, patients who dropped out during therapy reported a significantly higher degree of depression. Results did not differ between the four outpatient clinics and are comparable with the average effect-sizes reported by meta-analytic studies of controlled efficacy research, using selected patients. Also, restricting the sample according to the selection criteria often applied in research settings did not result in higher effect sizes for the applied outcome measures. We conclude that individual cognitive behavioural therapy for social phobia can be transported from research settings to the field of mental health.     

Evaluation of an intervention program for the reduction of bullying and victimization in schools

The present study evaluates the effect of an intervention program on the reduction of bullying and victimization in schools with a sample of 239 students aged 10–16 years old in Rome, Italy. The program deals with bullying and violence. It consists of three videos and a booklet that help students to develop the social cognitive competence skills to understand the negative consequences of aggressive behavior. The intervention was evaluated using an experimental design with pre‐test and post‐test analyses. Students were randomly allocated to experimental or control classes. Students completed a self‐report questionnaire in which they were asked to indicate on a 5–point scale how often they were victimized or bullied others. Victimization and bullying were assessed by using questions about specific types of actions, a composite measure of victimization and bullying, and a single question about victimization and bullying in general. Results showed that the program worked best for older students, but not for younger ones who in some cases reported an increased level of victimization after the intervention. For older students there was a decrease in victimization according to the sum of types of behavior for the experimental group, but an increase for the control group. The same result was found for direct victimization, having belongings stolen, and being called nasty names. Therefore, the program seemed to be beneficial for older students but possibly damaging for younger students. It is suggested that the program could have worked better with older students because of the cognitive skills it required. Younger students could have reported higher levels of bullying after the intervention because they became more sensitized to the topic of bullying. Aggr.

Birth-order and sex differences in the frequency of referral of children for psychological treatment: A partial replication and extension

A previous study of two-child families by Lahey, Hammer, Crumrine, and Forehand (1980) found that firstborn children were more likely to be referred for psychological treatment than second-borns and that males were more likely to be referred than females. Furthermore, there was a significant interaction between these two variables. In the present study, a new sample of two-child families from the same clinic was studied, confirming the previous findings of significant birth-order and sex effects but not the interaction. Separate analyses indicated that both birth-order and sex effects were significant for children given externalizing diagnoses, but only the birth-order effect was significant for heterogeneous internalizing diagnoses. Similarly, an analysis of only children revealed a significant sex effect for externalizers but not internalizers. A combined sample of two-child families independent of diagnosis (N=425)suggests that there are reliable associations of birth order and sex, but not the interaction, with referral rates in two-child families. Referred children were significantly more likely to have a female sibling than would be expected by chance, regardless of birth order or sex, suggesting that these children may look more deviant by comparison to female, vs. male, siblings, thus increasing the likelihood of clinic referral. The potential utility of birth order and sex as demographic marker variables for etiological research is discussed.     

A comparison of a modified sequential oral sensory approach to an applied behavior‐analytic approach in the treatment of food selectivity in children with autism spectrum disorder

Treatments of pediatric feeding disorders based on applied behavior analysis (ABA) have the most empirical support in the research literature (Volkert & Piazza, 2012); however, professionals often recommend, and caregivers often use, treatments that have limited empirical support. In the current investigation, we compared a modified sequential oral sensory approach (M‐SOS; Benson, Parke, Gannon, & Muñoz, 2013) to an ABA approach for the treatment of the food selectivity of 6 children with autism. We randomly assigned 3 children to ABA and 3 children to M‐SOS and compared the effects of treatment in a multiple baseline design across novel, healthy target foods. We used a multielement design to assess treatment generalization. Consumption of target foods increased for children who received ABA, but not for children who received M‐SOS. We subsequently implemented ABA with the children for whom M‐SOS was not effective and observed a potential treatment generalization effect during ABA when M‐SOS preceded ABA.     

Psychometric Properties of the Social Phobia and Anxiety Inventory, the Social Anxiety Scale for Adolescents, the Fear of Negative Evaluation Scale, and the Social Avoidance and Distress Scale in an Adolescent Spanish-Speaking Sample

The relationship among several social anxiety measures and a semistructured interview in an adolescent Spanish-speaking sample is examined. Construct validity and test-retest reliability were tested. A principal axis factor analysis was also explored. Results revealed good construct validity and alpha coefficients for the assessment instruments such as the Social Phobia and Anxiety Inventory (SPAI), the Social Anxiety Scale for Adolescents (SAS-A), the Fear of Negative Evaluation Scale (FNES) and the Social Avoidance Distress Scale (SADS). Among these, data strongly support the validity of the Social Phobia and Difference measures of the SPAI and Total SAS-A score as assessment measures in the adolescent population even in non-American cultures and languages. Furthermore, results appear to support the presence of a single higher-order dimension, social anxiety, as measured by the instruments used in this study.
