The structure of affective symptomatology in older adults with osteoarthritis

OBJECTIVE

To examine the structure of symptoms of affective disorder among older adults with a chronic health problem (osteoarthritis) and to explore cross-sectional and longitudinal associations of obtained affective symptom clusters with key health outcomes (pain, functional disability, perceived health).

METHODS

One-year longitudinal study of older adults with diagnosed osteoarthritis of the knee. Symptoms of DSM depression and anxiety were assessed in a research diagnostic interview by using a DSM-IV symptom checklist; self-reports captured demographic characteristics, objective health, pain, disability, and perceived health. Confirmatory factor analysis tested comparability of affective symptom structure in this sample to findings of previous research; ordinary least squares regression examined cross-sectional and longitudinal associations of affective symptoms with health outcomes, controlling for demographics and objective health.

RESULTS

The current sample displayed an affective symptom structure comparable with that observed in previous research, with symptoms clustering into depressed mood (DM), somatic symptoms (SS), and psychic anxiety (PA) factors. DM was cross-sectionally associated with pain and disability and marginally with perceived health; SS predicted current pain and perceived health. Only DM predicted 1 year change in disability and perceived health (but not pain).

CONCLUSIONS

This research confirms the role of SS of distress in fueling disability and perceived ill health among older adults who are chronically ill. However, it is DM that drives changes in perceived health and functional ability.

Predictors of DSM and Fagerstrom-defined nicotine dependence in African American and Puerto Rican young adults

This study examined the psychosocial predictors of nicotine dependence, as defined by a variant of the criteria employed in the DSM-IV-specifically that of the University of Michigan Composite International Diagnostic Interview (UM-CIDI)-and the Fagerstrom Test for Nicotine Dependence (FTND). The study was conducted with a community sample of African American and Puerto Rican young adults (N = 475; mean age = 26). Predictor variables included physiologically based psychosocial (i.e., depressive symptoms and family problems with smoking) as well as social-behavioral psychosocial (i.e., rebelliousness and partner's problems with smoking) predictors of nicotine dependence. Using multiple regression analyses, UM-CIDI-defined dependence was predicted by each of the four psychosocial variables, while FTND-defined dependence was predicted only by the social-behavioral variables. These findings bear out the disparate dimensions of nicotine dependence each measure taps. Research and clinical implications of the findings are discussed, and the study's limitations are noted.
