A depressive symptom scale for the California Psychological Inventory: construct validation of the CPI-D.
ABSTRACT To facilitate life span research on depressive symptomatology, a depressive symptom scale for the California Psychological Inventory (CPI) is needed. The authors constructed such a scale (the CPI-D) and compared its psychometric properties with 2 widely used self-report depression scales: the Beck Depression Inventory and the Center for Epidemiological Studies Depression Scale. Construct validity of the CPI-D was examined in 3 studies. Study 1 established content validity, classifying CPI-D items into Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition depressive symptoms. Study 2 used 3 large samples to gather evidence for reliability and validity: correlational analyses demonstrated alpha reliability and convergent and discriminant validity; factor analysis provided evidence for discriminant validity with anxiety; and regression analyses demonstrated comparative validity with existing standard PI scales. Study 3 used clinician ratings of depression and anxiety as criteria for external validity.

ABSTRACT: Despite anecdotal evidence suggesting that air travel is personally demanding, little research has examined air travel stress. To address these issues, the author developed and evaluated the 1st known measure of air travel stress--the Air Travel Stress Scale--in 3 studies. Exploratory and confirmatory factor analysis indicated 3 components: (a) anxious reactions to adverse air travel events, (b) angry reactions to other passengers as well as an antecedent of air travel stress, and (c) the lack of trust that the airlines/airports will ensure one's comfort and safety. Each component had good internal reliability and test-retest reliability over a 6- to 7-week interval. Each component showed evidence for discriminant and convergent validity. Implications for research into understanding and intervening on air travel stress are discussed.

ABSTRACT: The objective of this study was to develop and validate the Depression Scale for the Elderly. An explanatory theoretical model was developed for depression, consisting of three categories: cogni- tive, affective, and somato-motor. The items elab- orated thusly were submitted to semantic analy- sis and judges. The pilot instrument was applied to 340 subjects, 88% of whom were females, most- ly with complete primary education (67.9%), and a mean age of 63.74 (SD = 6.87) years. The sam- ple also responded to the Beck Depression Index (BDI). Validation of the scale was based on factor analyses (Principal Axis Factoring) and analysis of the items' internal consistency (Cronbach's al- pha). Multiple regressions evaluated the predic- tive power of the factors in the depression scale for the elderly on the final BDI score. Scale vali- dation demonstrated that the depression scale for the elderly is composed of two factors: cogni- tive-affective and somato-motor, which explain 53% of the BDI (convergent validity). One can thus state that the depression scale for the elderly consists of factors that assess different aspects of the depression construct (factor validity), which present internal consistency indices within the psychometric standards.Cadernos De Saude Publica - CAD SAUDE PUBLICA. 01/2008; 24(5).

ABSTRACT: When interest in self-esteem exploded in the 1980s, many longitudinal studies were already under way and thus did not administer self-esteem measures. Consequently, not much is known about the developmental course of self-esteem during adulthood. In order to facilitate life-span research using existing longitudinal studies, a new self-esteem scale (CPI-SE) was derived from the California Psychological Inventory. Study 1 documented the internal consistency and test – retest reliability of the CPI-SE, as well as its convergent validity by comparing it to three commonly used measures of self-esteem. Study 2 examined the nomological network of the CPI-SE by relating it to interviewer ratings of self-esteem, affect, coping style, social skills, intelligence, and physical attractiveness, obtained with the California Adult Q-Set. Together, these two studies provide evidence for the construct validity of the CPI-SE.Self and Identity 01/2007; 6(1):20-40. · 1.42 Impact Factor
