Comorbidity of anxiety and depression in children and adolescents.

Anxiety and depression in children and adolescents are reviewed, including differential diagnosis, assessment of symptoms, family history data, developmental features, and clinical correlates. Findings indicate that 15.9% to 61.9% of children identified as anxious or depressed have comorbid anxiety and depressive disorders and that measures of anxiety and depression are highly correlated. Family history data are inconclusive. Differences emerged among children with anxiety, depression, or both disorders. Anxious children were distinguishable from the other 2 groups in that they showed less depressive symptomatology and tended to be younger. The concurrently depressed and anxious group tended to be older and more symptomatic. In this group, the anxiety symptoms tended to predate the depressive symptoms. Findings are discussed in the context of a proposed developmental sequence.

Comorbidity and treatment planning: summary and future directions.

This summary blends the commentaries from the 6 articles in the special section on comorbidity. Included is a discussion of various definitions of comorbidity, the merits and demerits of a hierarchical diagnostic system, and consideration of the extent, patterning, and nature of comorbidity. Directive comments with reference to future intervention planning mention both assessment (distinguishing overlapping constructs) and treatment (sequencing and treatment manuals) issues.

Psychological and pharmacological therapy: methods and modes for comparative outcome research.

Psychological and pharmacological comparative outcome studies are reviewed, typically using select examples of cognitive-behavioral interventions from among the psychological therapies and of depression from among the disorders. Special attention is given to methodological considerations such as selecting outcome measures, calibrating the quality of therapy, and investigating client and therapist characteristics and the therapeutic relationship. Discussion includes consideration of various modes of comparison (i.e., quickness of action, side effects, relapse, compliance, cost-effectiveness) that may be used in comparative outcome studies. A disorder-specific approach to comparative outcome research is seen as a necessary step in the progress toward an increasingly sophisticated discrimination of distinctive, complementary, and interactive therapeutic processes.

Child therapy: issues and recommendations.

When children or adolescents are clients in receipt of psychological treatment, there are specific issues that require attention. With regard to assessment and diagnosis, researchers and clinicians alike must pay attention to variations across sources of assessment data, the comorbidity of diagnoses, and the potential utility of a "family" (as opposed to child) diagnosis. Considerations of "Who is the client?" and the role of the therapeutic relationship in child therapy are discussed. Specific methodological recommendations regarding randomized clinical trials, control groups, the selection of dependent variables, the manualization of treatments, and the use of tests of clinical and statistical significance are presented. Specific topics for research are recommended.

Cognitive deficit or cognitive distortion in childhood depression.

Three studies were conducted to evaluate cognitive disturbance and depression in children. In Study I, 47 sixth-grade children, including 17 who received a DSM-III diagnosis of depression, and their parents were independently interviewed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children, and they completed the Parent-Child Depression Inventory. Children completed the Children's Depression Inventory, the Matching Familiar Figures Test, and the My Standards Questionnaire. Results of Study I were consistent across raters and measures: Depression was associated with a negative style of processing self-evaluative information, while being unrelated to a processing deficit. A second study was initiated to replicate the results of Study 1 and to extend them to a wider age range of children. Thirty-eight third-, fourth-, fifth-, and sixth-grade children, half of whom were depressed and half of whom indicated a minimum of depressive symptomatology on the Children's Depression Inventory, completed the Matching Familiar Figures Test and the My Standards Questionnaire. Results were very similar to those found in Study 1. A third study was conducted to test whether the self-perceptions of depressed children were accurately negative or negatively distorted, as judged against their teachers' observations of them. Results supported the hypothesis that depressed children exhibit a distorted style of processing self-evaluative information. The implications of the results for theory and treatment were discussed.

Elevated platelet MAO is related to impulsivity in disruptive behavior disorders.

Platelet monoamine oxidase (MAO) activity was measured in 32 drug-free prepubertal boys with externalizing symptoms of disruptive behavior disorders and 47 boys with no DSM-III-R diagnoses, and correlated to questionnaire and laboratory performance measures of impulsivity. A subgroup of boys with high MAO activity exhibited significantly poorer performance (i.e., more impulsivity) than a subgroup of low MAO activity on laboratory tasks requiring response inhibition. High MAO patients were more impulsive than high MAO controls on some performance tasks and elevated platelet MAO was unrelated to personality questionnaire measures of impulsivity or to patient status. These data suggest that biological markers such as MAO activity may correlate better with performance than clinical questionnaire measures. Abnormally high platelet MAO activity may not be sufficient to produce externalizing symptoms in children, perhaps interacting with an underlying behavioral dimension of impulsivity.

Psychological aspects of patient education for stressful medical procedures.

Psychological preparation for stressful medical procedures is becoming more and more common, and health educators frequently design and implement many of these programs. This article summarizes many of the issues relevant to these patient education programs. Individual differences among patients and their differential responses to types of interventions are emphasized, and descriptions of information provision, skills training, relaxation training/desensitization, modeling, self-statement modification interventions are provided.

Short form and factor-analytic studies of the WISC-R with behavior problem children.

Two analyses of the WISC-R protocols of 100 children referred for behavioral problems in school were conducted to study (a) the utility of a variety of WISC short forms and (b) the factor structure of the WISC-R. Although the correlations between short form and WISC-R IQs were highly significant, mean differences and a high percentage of IQ classification changes indicated that the short forms were not acceptable WISC-R substitutes. Different factor analyses consistently evidenced two factors, Verbal Comprehension and Perceptual Organization, which corresponded perfectly to the Verbal and Performance.

Analyses of changes in verbal behavior following a cognitive-behavioral treatment for impulsivity.

Analyses were conducted to examine further the results of a cognitive-behavioral treatment for impulsivity in emotionally disturbed children (Kendall & Finch, 1978). The verbal behaviors of treated impulsive children, impulsive controls, and reflective children, recorded during MFF performance at pretreatment, posttreatment, and follow-up, were examined. The results indicated nonsignificant effects for several specific codes; however, the impulsive children that had received treatment evidenced a significant increase in total on-task verbal behavior at posttreatment. Discussion includes a consideration of these findings in regard to the efficacy of the cognitive-behavioral treatment and the need for research on the assessment of cognitive variables in children.

Sex differences in anxiety response and adjustment to dental surgery: effects of general vs. specific preoperative information.

Monitored anxiety level by the State-Trait Anxiety Inventory and Corah's (1969a) dental anxiety scale and evaluated adjustment via behavioral ratings, in 32 female and 31 male dental surgery patients who were presented general or specific information prior to surgery. The findings indicated that dental surgery is a stressful procedure that elicits comparably high levels of state anxiety in males and females. For most patients, even those high in dental anxiety, state anxiety level returns to "normal" levels just after the completion of surgery. The dental anxiety scale administered well before surgery is a good predictor of patient anxiety level in the dental situation, especially for males. Females responded to an informational tape received prior to surgery with increased anxiety, and were rated as showing poorer overall adjustment in surgery than males. The general and specific information tapes did not differentially affect adjustment, but informational input and related variables such as patient expectancies and prior level of information are factors that need further investigation in terms of their potential relevance for the reduction of patient anxiety and enhancement of patient adjustment during dental procedures.

Note on locus of control and academic achievement in institutionalized juvenile delinquents.

The previously reported relationship between internal locus of control and academic achievement was explored with the Nowicki-Strickland Locus of Control Scale for Children (Nowicki & Strickland, 1973) and seven measures of academic achievement in a random sample of 45 male residents of seven state learning centers for juvenile delinquents. Correlations between overall locus of control scores and all seven measures were significant, but with intelligence controlled in a partial correlation, locus of control scores were found to add little to the prediction of academic achievement from IQ scores alone. Discussion addressed possible explanations for the current findings in terms of the meaning of the scale for a nonnormal group and the effects of situations on responses of subjects.
