The Relationship Quality Interview: evidence of reliability, convergent and divergent validity, and incremental utility.

Relationship satisfaction and adjustment have been the target outcome variables for almost all couple research and therapies. In contrast, far less attention has been paid to the assessment of relationship quality. The present study introduces the Relationship Quality Interview (RQI), a semistructured, behaviorally anchored individual interview. The RQI was designed to provide a more objective assessment of relationship quality as a dynamic, dyadic construct across 5 dimensions: (a) quality of emotional intimacy in the relationship, (b) quality of the couple's sexual relationship, (c) quality of support transactions in the relationship, (d) quality of the couple's ability to share power in the relationship, and (e) quality of conflict/problem-solving interactions in the relationship. Psychometric properties of RQI ratings were examined through scores obtained from self-report questionnaires and behavioral observation data collected cross-sectionally from a sample of 91 dating participants and longitudinally from a sample of 101 married couples. RQI ratings demonstrated strong reliability (internal consistency, interrater agreement, interpartner agreement, and correlations among scales), convergent validity (correlations between RQI scale ratings and questionnaire scores assessing similar domains of relationship quality), and divergent validity (correlations between RQI scale ratings and (a) behavioral observation codes assessing related constructs, (b) global relationship satisfaction scores, and (c) scores on individual difference measures of related constructs). Clinical implications of the RQI for improving couple assessment and interventions are discussed.

Predictors of loneliness in caregivers of persons with Parkinson's disease.

This study examined loneliness among caregivers of individuals with Parkinson's disease (PD). The sample included 70 caregivers (74% female; 96% spouses) who were currently living with the patient. A postal survey was sent to caregivers of persons with PD on the mailing list of a regional Parkinson association; response rate was 39%. Assessment instruments included the UCLA Loneliness Scale, Social Provisions Scale, Hoehn and Yahr (caregiver version), a perceived Self-Efficacy Scale developed previously for use with PD caregivers, and questions related to both patient and caregiver characteristics. Caregivers reported more loneliness than all similar normative groups except Alzheimer caregivers (P<0.001 to P=0.011). Hierarchical regression analyses were used to determine whether patient or caregiver characteristics were more predictive of loneliness. Results indicated that patient variables accounted for only 12% of the variance in loneliness, whereas caregiver variables accounted for an additional 46% of the variance (P<0.01). Among the significant individual caregiver predictors of greater loneliness were less education, lower perceived self-efficacy (both P<0.05) and poorer physical health (P<0.01). It was also found that persons attending caregiver support groups reported less loneliness (P<0.05) and more perceived support (P<0.05) than those not attending support groups. Because loneliness was significantly predicted by caregiver rather than patient variables, it is possible that strategic interventions for caregivers could ameliorate loneliness.

Objective Ratings of Relationship Skills across Multiple Domains as Predictors of Marital Satisfaction Trajectories.

Expanding upon social-learning and vulnerability-stress-adaptation approaches to marriage, the impact of multiple dyadic behaviors on marital satisfaction trajectories was examined in 101 couples. Semi-structured interviews were administered separately to husbands and wives at 3 months of marriage. Interviewers generated objective ratings for five domains: emotional closeness/intimacy, sexual intimacy/sensuality, interspousal support, decision-making/relational control, and communication/conflict management. Marital satisfaction was assessed four times over three years. Dyadic behaviors were associated with initial levels and rates of change in satisfaction, demonstrating the unique contributions of each relational skill on marital development. For husbands, sexual intimacy was the strongest predictor of change whereas for wives, communication/conflict management was the strongest predictor of change compared to other domains. Theoretical, methodological and clinical implications are discussed.
