Development of a brief measure to assess quality of life in obesity.

Abstract: KOLOTKIN, RONETTE L., ROSS D. CROSBY, KARL D. KOSLOSKI, AND G. RHYS WILLIAMS. Development of a brief measure to assess quality of life in obesity. Obes Res. 2001;9:102‐111. Objective: Obesity researchers have a growing interest in measuring the impact of weight and weight reduction on quality of life. The Impact of Weight on Quality of Life questionnaire (IWQOL) was the first self-report instrument specifically developed to assess the effect of obesity on quality of life. Although the IWQOL has demonstrated excellent psychometric properties, its length (74 items) makes it somewhat cumbersome as an outcome measure in clinical research. This report describes the development of a 31-item version of the IWQOL (IWQOL-Lite). Research Methods and Procedures: IWQOLs from 996 obese patients and controls were used to develop the IWQOL-Lite. Psychometric properties of the IWQOL-Lite were examined in a separate cross-validation sample of 991 patients and controls. Results: Confirmatory factor analysis provided strong support for the adequacy of the scale structure. The five identified scales of the IWQOL-Lite (Physical Function, SelfEsteem, Sexual Life, Public Distress, and Work) and the total IWQOL-Lite score demonstrated excellent psychometric properties. The reliability of the IWQOL-Lite scales ranged from 0.90 to 0.94 and was 0.96 for the total score. Correlations between the IWQOL-Lite and collateral measures supported the construct validity of the IWQOL-Lite. Changes in IWQOL-Lite scales over time correlated significantly with changes in weight, supporting its sensitivity to change. Significant differences in IWQOL-Lite scale and total scores were found among groups differing in body mass index, supporting the utility of the IWQOL-Lite across the body mass index spectrum. Discussion: The IWQOL-Lite appears to be a psychometrically sound and clinically sensitive brief measure of quality of life in obese persons.

Antecedents of workplace emotional labor dimensions and moderators of their effects on physical symptoms

Abstract: The present study distinguished between two modal emotional display rules, demands to express positive efference and demands to suppress negative efference, that partially constitute the work roles of many employees. Perceived demands to express positive emotion were positively related to health symptoms primarily among those reporting: (1) lower identification with the organization; (2) lower job involvement; and (3) lower emotional adaptability. The effects of various personality traits and situational variables on perceived emotional labor differed depending on the nature of the emotional labor. The findings are discussed in terms of implications of emotional labor for health and practices through which organizations might intervene to minimize its unhealthful consequences among employees. We also attempt to reconcile the findings with some of the related research in psychology suggesting that some forms of required efference may have salutary physiological consequences.
