Comparative construct validity of three presenteeism instruments in workers with musculoskeletal complaints: a prospective cohort study.

ABSTRACT: OBJECTIVES:To compare the construct validity of three presenteeism instruments, using health and economic outcomes as external references, among working persons reporting musculoskeletal complaints. METHODS:Data from the prospective Study on Transitions in Employment, Ability and Motivation were used. Presenteeism measurement comprised a global rating of work-ability, and two instruments indicating at-work productivity, and was assessed yearly over 6 years of follow-up. Longitudinal associations between measures of health and subsequent presenteeism, and between presenteeism and subsequent days of sick leave were assessed using generalised estimating equation models. The effect of groups of contextual factors (socio-demographic, lifestyle, personal and work-related factors) was investigated by assessing the change in explained variability. RESULTS:In total, 4523 persons were analysed. The association between physical health and work-ability was stronger than both at-work productivity measures; 10 points increase in physical health (0-100, higher is better) was associated with 0.79 points (95% CI 0.75 to 0.84) better work-ability (0-10, higher is better) in the subsequent year. Besides, work-ability best predicted sick leave; one point higher work-ability was associated with 4 days less sick leave (95% CI -5.09 to -3.63) the subsequent year. Personal factors improved model fit for models on health and work-ability, but conflicting results were seen for both at-work productivity instruments. CONCLUSION:Work-ability showed higher construct validity against health and economic outcomes as compared to at-work productivity, which shows that work-ability is different to productivity (losses). Personal factors are especially relevant when interpreting the relation between health and work-ability or self-reported quantity of work.

Project description:BackgroundPsychological alienation is an important concept in the study of adolescents' health and behavior but no gold standard for measuring alienation among adolescents exists. There is a need for new scales with high validity for use in adolescent health and social research. The purpose of the present study was to develop and validate alienation scales in accordance with Seeman's conceptualization of alienation focusing on three independent variants specifically relevant in adolescent health research: powerlessness, meaninglessness and social isolation.MethodsCross-sectional data from 3083 adolescents aged 13 to 15 years from the Danish contribution to the cross-national study Health Behaviour in School-aged Children (HBSC) were used. We identified and developed items, addressed content and face validity through interviews, and examined the criterion-related construct validity of the scales using graphical loglinear Rasch models (GLLRM).ResultsThe three scales each comprised three to five face valid items. The powerlessness scale reflected the adolescent's expectancy as to whether his/her behavior can determine the outcome or reinforcement he/she seeks. The meaninglessness scale reflected the expectancy as to whether satisfactory predictions regarding the effects of one's behavior are possible. Finally, the social isolation scale reflected whether the adolescent had a low expectancy for inclusion and social acceptance. All scales contained some uniform local dependency and differential item functioning. However, only to a limited degree, which could be accounted for using GLLRM. Thus the scales fitted GLLRMs and can therefore be considered to be essentially construct valid and essentially objective.ConclusionThe three alienation scales appear to be content and face valid and fulfill the psychometric properties of a good construct valid reflective scale. This suggests that the scales may be appropriate in future large-scale surveys to examine the relation between alienation and a range of adolescent health outcomes such as health, behavior and wellbeing.

Project description:The psychometric properties of Patient Reported Outcomes Measurement Information System (PROMIS) instruments have been explored in a number of general and clinical samples. No study, however, has evaluated the psychometric function of these measures in individuals with symptomatic knee osteoarthritis (KOA). The aim of this project was to evaluate the construct (structural) validity and floor/ceiling effects of four PROMIS measures in this population.We conducted a secondary analysis of baseline data from a randomized trial comparing Tai Chi and physical therapy. Participants completed four PROMIS static short-form instruments (i.e., Anxiety, Depression, Physical Function, and Pain Interference) as well as six well-validated (legacy) measures that assess pain, function, and psychological health. We calculated descriptive statistics and percentages of participants scoring the minimum (floor) and maximum (ceiling) possible scores for PROMIS and legacy measures. We also estimated the association between PROMIS scores and scores on legacy measures using Spearman's rank correlations coefficients.Data from 204 participants were analyzed. Mean age of the sample was 60 years; 70% were female. The PROMIS Anxiety and Depression had floor effects with 17 and 24% of participants scoring the minimum, respectively. PROMIS Anxiety and Depression scores had strongest associations with general mental health, including stress (Perceived Stress Scale, r???0.65) and depression (Beck Depression Index-II, r?=?0.70). PROMIS Pain Interference scores correlated most strongly with measures of whole body pain (Short-Form 36 Bodily Pain, r?=?-0.73) and physical health (Short-Form 36 Physical-Component Summary, r?=?-0.73); their correlations were lower with other legacy measures, including with the WOMAC knee-specific pain (r?=?0.47). PROMIS Physical Function scores had stronger associations with scores on the Short-Form 36 Physical Function (r?=?0.79) than with scores on other legacy measures.The four PROMIS static-short forms performed well among individuals with symptomatic knee osteoarthritis as evidenced in correlations with legacy measures. PROMIS Anxiety and Depression target general mental health (e.g., stress, depression), and PROMIS Pain Interference and Physical Function static-short forms target whole-body outcomes among participants with symptomatic knee osteoarthritis. Floor effects in the PROMIS Anxiety and Depression scores should be considered if needing to distinguish among patients with very low levels of these outcomes.Clinicaltrials.gov NCT01258985.

Project description:BackgroundPeople with hemophilia (PWH) experience frequent joint bleeding, resulting in pain and functional impairment. Generic and disease-specific patient-reported outcome (PRO) instruments have been used in clinical studies, but rarely in the comprehensive hemophilia care setting.ObjectiveThe objective of this study was to assess construct validity of PRO instruments measuring pain, functional impairment, and health-related quality of life in US PWH with a history of joint pain/bleeding.MethodsAdult male PWH completed 4 PRO instruments (EQ-5D-5L with visual analog scale, Brief Pain Inventory v2 Short Form [BPI], SF-36v2, Hemophilia Activities List [HAL]) and underwent a musculoskeletal examination (Hemophilia Joint Health Score v2.1 [HJHS]). Construct validity between index and domain scores was evaluated by Pearson product-moment correlation coefficient.ResultsA total of 381 PWH were enrolled. EQ-5D-5L Mobility correlated with BPI, SF-36v2, and HAL domains related to pain, physical function, and activity of the lower extremities. EQ-5D-5L Self-Care correlated only with HAL Self-Care. EQ-5D-5L Usual Activities correlated with BPI Pain Interference and domains within SF-36v2 and HAL related to pain and physical function/activities (particularly those involving the lower extremities). EQ-5D-5L Pain/Discomfort correlated with Bodily Pain and Physical Summary on SF-36v2, HAL Overall Activity, and all BPI pain domains. EQ-5D-5L Anxiety/Depression correlated with social/emotional/mental aspects of SF-36v2. On BPI, most pain domains correlated with Bodily Pain and Physical Health Summary on SF-36v2 and Overall Activity on HAL. On SF-36v2, Physical Functioning, Role Physical, Bodily Pain, and Physical Health summary scores correlated with all the domains of HAL except Self-Care. For HJHS, Ankle and Total scores correlated with SF-36v2 Physical Functioning and HAL Lying/Sitting, Leg Function, Complex Lower Extremity Activity, and Overall Activity.ConclusionAll PRO instruments have high construct validity but provide different levels of detail in describing effects of hemophilia. Instrument choice may depend on individuals' symptoms, treatment planning goals, or outcome tracking research objectives, with consideration for administrative burden.
