Sequential cognitive-behavioral therapy for children with obsessive-compulsive disorder with an inadequate medication response: a case series of five patients.

Few data have been reported on the efficacy of cognitive-behavioral therapy (CBT) for youth with obsessive-compulsive disorder (OCD) who have not responded to prior treatment with medication. Given this, we report an open trial of CBT for children who have remained symptomatic following medication trials. Five children with OCD who had an inadequate response to psychotropic medications (e.g., limited response and/or unable to be titrated to a complete dose due to side effects) received treatment in a 3-week intensive CBT program. Assessments were conducted at baseline and after treatment. All participants were classified as treatment responders (much improved or very much improved) and the severity of clinician-rated OCD symptoms and impairment significantly decreased after the intervention. Although a number of limitations of this preliminary report exist, this study provides preliminary support for the utility of an intensive intervention for youth with OCD who have had an inadequate response and/or adverse side effects.

Reliability and validity of the Child Behavior Checklist Obsessive-Compulsive Scale.

This study examined the psychometric properties of the Obsessive-Compulsive Scale (OCS) of the Child Behavior Checklist (CBCL). Participants included 48 youth with obsessive-compulsive disorder (OCD), 41 with a non-OCD internalizing disorder, and 101 with an externalizing disorder. Confirmatory factor analysis of the 8-item OCS did not result in an adequate fit. Exploratory factor analysis identified a 1-factor model consisting of 6 items. Adequate internal consistency for the revised OCS (OCS-R) was obtained, and convergent validity was supported by moderate relationships with other OCD indices. The OCS-R had stronger associations with measures of OCD symptoms than with measures of depression and externalizing behaviors. Youth with OCD had significantly higher OCS-R scores than those with internalizing and externalizing disorders. Suggestions for cutoff scores are provided using results from ROC analyses. Overall, these findings suggest that the OCS-R is a reliable and valid instrument for the assessment of pediatric OCD.

Psychometric evaluation of the social experience questionnaire in adolescents: descriptive data, reliability, and factorial validity.

This study evaluated the psychometric properties of the Social Experience Questionnaire (SEQ) in a sample of 1158 adolescents aged 13-17 years. Confirmatory factor analysis fit indices supported the hypothesized three-factor model of the SEQ that assesses overt and relational victimization, and prosocial behaviors from peers. Analyses of gender differences revealed that boys reported being overtly victimized more than girls, and girls reported greater receipt of prosocial behaviors from peers than boys. No gender differences in relational victimization were found. The internal consistency was adequate across gender, and test-retest stability over 12 months was modest. Intercorrelations among overt and relational victimization subscales suggest that these subscales assess related, but relatively independent constructs of peer victimization. These findings support the use of the SEQ with adolescents.

Factor analytic study of the Children's Yale-Brown Obsessive-Compulsive Scale.

This study examined the psychometric properties of the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS; Scahill et al., 1997). Participants were 82 children and adolescents diagnosed with obsessive-compulsive disorder (OCD). Confirmatory factor analyses of 2 previously found models (Obsessions and Compulsions; Disturbance and Severity) yielded poor fit indexes. Exploratory factor analysis supported a model of severity and disturbance with slightly different item content than found by McKay et al. (2003). The internal consistency of the factors was acceptable, and the convergent and divergent validity was supported vis-a-vis correlations with clinician ratings of impairment, self-report measures of depression and anxiety, and parent ratings of Tourette's disorder (TD) symptoms. These findings suggest that the CY-BOCS Total Score may represent an inaccurate assessment of symptom severity and supports the use of the revised Severity and Disturbance factors in assessing illness severity.

Developmental considerations in the context of pediatric transplantation.

This paper describes important psychological and psychosocial considerations in pediatric transplantation that can be valuable for all pediatric health care providers in the transplant setting. A developmental perspective is necessary in the consideration of these implications throughout the transplant process. Each age range (infancy, toddler and preschool, school age, and adolescence) is discussed with its normal associated developmental milestones as well as the impact transplantation can have on these milestones. Appropriate evaluation and referrals are also explained in the context of the pediatric transplant setting.

A factor analytic study of the loneliness and social dissatisfaction scale in a sample of African-American and Hispanic-American children.

This study investigated the psychometric properties of the Loneliness and Social Dissatisfaction Scale (LSDS) in a sample of African-American and Hispanic-American children. Participants were a non-clinical sample ( N = 186) of children ages 11 to 13 in the fifth and sixth grades in a school in the Metropolitan New York area. Confirmatory factor analyses revealed a two-factor model fits the sample data better than a one-factor model. Internal consistencies were acceptable across the two factors, and convergent validity of the LSDS was supported by a moderately positive relation with a self-report measure of depressive symptomatology. In a structural equation model, ethnicity, grade, and gender predicted little variance in each LSDS factor, suggesting little measure bias. These preliminary findings suggest that the LSDS is a psychometrically sound instrument for African-American and Hispanic-American children, yet future inspection of its factor structure in more diverse samples of children is warranted.

Association between overt and relational aggression and psychosocial adjustment in undergraduate college students.

This study examined the relations between overt and relational aggression, social anxiety, loneliness, depressive symptoms, and alcohol and drug use in a sample of 287 undergraduate college students. Consistent with prior work, men reported engaging in more overt aggression than women. Contrary to our predictions, men also reported engaging in more relational aggression than women. Results also indicated that overt and relational aggression were positively associated with social anxiety, loneliness, depressive symptoms, alcohol use, and drug use for the overall sample. Hierarchical regression analyses showed positive relations between overt aggression and alcohol use for men and no relations between relational aggression and any psychosocial adjustment index. For women, overt aggression uniquely predicted social anxiety, loneliness, and depressive symptoms, whereas relational aggression uniquely predicted social anxiety, loneliness, depression, and alcohol and drug problems. Implications of these findings are discussed in terms of the role of peer aggression in students' psychosocial adjustment.

Language comprehension and working memory language comprehension and working memory deficits in patients with schizophrenia.

The present study examined the hypothesis that patients with schizophrenia have deficits in language comprehension compared to normal controls, and that these deficits are associated with disturbances in working memory (WM). In addition, we hypothesized that language comprehension deficits would be associated with the severity of specific symptoms in the patients (formal thought disorder and hallucinations). Participants were 27 stable outpatients with schizophrenia and 28 demographically similar controls. Language comprehension was measured by presenting sentences auditorily that varied in length and syntactic complexity, followed by two or three comprehension questions. We measured working memory by administering a reading span task. Results indicated that, as predicted, language comprehension deficits were significantly greater in patients with schizophrenia than controls. Also as predicted, working memory was strongly correlated with language comprehension performance in both patients with schizophrenia and controls. Contrary to our predictions, language comprehension and working memory deficits were not associated with either formal thought disorder or hallucinations.

Father involvement in parent training: when does it matter?

We examined the impact of father involvement on treatment. Participants were 107 families enrolled in parent-child interaction therapy (PCIT), including 56 involved-father (IF) families, 16 uninvolved-father (UF) families, and 35 absent-father (AF) families. All groups showed improvements during treatment to within the average range on the Eyberg Child Behavior Inventory (ECBI), although mothers from AF families reported better treatment outcome than mothers from IF families. Improvements occurred on the Beck Depression Inventory (BDI) and the Parenting Stress Index (PSI) as well, but there were no group differences. At a 4-month follow-up, mothers in IF families maintained treatment gains on the ECBI. In contrast, mothers in AF families reported significant decline at follow-up, although their scores remained within the normal range. Results suggest that father participation in treatment may not affect immediate treatment outcome but may help to maintain the beneficial effects of PCIT.
