Normative and reliability data for the children's depression inventory

The present study was undertaken to examine some of the psychometric properties of the Children's Depression Inventory (CDI), a self-report inventory devised by Kovacs and Beck (1977) to measure depression in children and adolescents. Normative and reliability data were obtained from three independent samples taken from eight public schools in central Pennsylvania. Age- and gender-related differences in reported characteristics of depression were also investigated. The subjects were 594 males and 658 females whose ages ranged from 8 to 16 years and whose combined mean age was 11.67 years (SD=1.91). The CDI was group-administered to all 1,252 subjects; 155 fifth-grade subjects (77 males and 78 females) were retested after 3 weeks, and 107 seventh- and eight-grade subjects (45 males and 62 females) were retested after 1 year. The distribution statistics for the combined samples yielded an overall CDI mean of 9.09, a standard deviation of 7.04, and a cutoff score of 19 for the upper 10% of the distribution. Reliability assessed through coefficient alpha, item-total score product-moment correlations, and test-retest coefficients proved acceptable. Gender differences were obtained for several item-total score correlations and for test-retest reliability of CDI scores.     

Exercise Stage of Change and Self-Efficacy in Primary Care: Implications for Intervention

Multiple chronic diseases are caused or complicated by a sedentary lifestyle. Thus, an important and challenging application of psychology in clinical settings is changing the behavior of sedentary primary care patients. This study focused on exercise stage of change and self-efficacy in a sample of adult family practice patients recruited while waiting for their scheduled physician appointment. Regarding exercise stage of change, 15% of respondents were in the Precontemplation stage, 26% in the Contemplation stage, 50% in the Preparation stage, 7% in the Action stage, and 13% in the Maintenance stage. Mean self-efficacy scores for exercise were significantly higher among respondents in the Action and Maintenance stages of change. These cross-sectional data are consistent with the hypothesis that movement through the exercise stages of change could be encouraged by clinical interventions that increase exercise self-efficacy. The identification of multiple personal opportunities for increasing exercise self-efficacy may be clinically useful in this context. Recommendations for psychologists in primary care settings in their work with physicians are offered.     

Stability of older adults' preferences for life-sustaining medical treatment.

The use of instructional advance directives assumes that preferences for life-sustaining medical treatment remain stable over time and across changes in life condition. A sample of 332 older adults recorded their preferences for 4 life-sustaining treatments in 9 illness scenarios. These preferences were elicited again 1 and 2 years after the original interview. Overall, preferences for life-sustaining treatment were moderately stable over time, but stability varied significantly across judgments. Preferences were most stable for illness scenarios that were most and least serious and for decisions to refuse treatment. Age, gender, education, and prior completion of an advance directive were all related to preference stability, and evidence indicated that declines in physical or psychological functioning resulted in decreased interest in life-sustaining treatment.
