Development and Psychometric Investigation of Career Problems Inventory for Bipolar Disorder Patients

Abstract

Background In order to measurement of career problems of bipolar mood patients, this study was performed on the 108 people that were selected by purposeful sampling, which were consisted of two sample groups (non-clinical participants, N = 53) and (bipolar participants, N = 55). Method: The inventory is including 81 items. In order to determine reliability of CPI-BD was used internal consistency and temporal stability method. Factor analysis was investigated and content, construct and convergent validity of the CPI-BD was evaluated. Results Coefficient Cronbach's alpha was .81 (non-clinical participants, N = 53) and .96 (bipolar participants, N = 55), (p < 0.05) and showed good internal consistency. Also in temporal stability method test-retest reliability about 7 weeks later, includes 35 participants from both the non-clinical participants and bipolar patients obtaining a reliability coefficient of .91 (p < 0.01). Convergent validity of this inventory was examined with Bipolar Disorder Subtle Symptoms Inventory (BD-SSI) and correlation coefficient was obtained r = .79 (non-clinical participants, N = 53) and r = .78 (bipolar participants, N = 55) (p < 0.01). In exploring factor analysis using varimax rotation nine sub-scales were extracted including: communication problems, poor work performance, insecurity, grandiosity, unreliability, change seeking, vulnerability, lack of boundary, lack of self-control with opposite sex. Conclusion The career problems inventory–bipolar disorder form is a valid and reliable inventory to measure career problems among bipolar patients.

Development and Psychometric Investigation of Career Problems Inventory for Bipolar Disorder Patients

“…The BDSI is a 74 items self-reported inventory used to assess the subtle symptoms of bipolar disorder [32]. The participant is asked to answer with yes (1) or no (0) according to "how much they were affected by the item over their past life".…”

“…As mentioned in the item generation section content validity of the CPI-BD was investigated and con rmed by ve psychologists who were expert in bipolar disorder and career counseling research. Convergent validity of the CPI-BD was investigated by estimating the correlation coe cients between the CPI-BD and its subscales and bipolar disorder symptom inventory BDSI [32]. The total CPI-BD in non-clinical participants and bipolar participants respectively was correlated with the BDSI (r= .79, P< .000, N=53), (r= .78, P< .000, N=55) respectively.…”
