Brief report: Testing measurement invariance and differences in self‐concept between adolescents with and without physical illness or developmental disability

Abstract: The aim of this study was to test for measurement invariance and examine differences in global self‐concept between adolescents with and without physical illness or developmental disability. The sample consisted of adolescents 10–19 years who participated in the Canadian National Longitudinal Survey of Children and Youth (N = 8491). Multiple group confirmatory factor analysis was used to test for measurement invariance. Twenty‐three percent (n = 1966) of participants had a physical illness or developmental dis… Show more

“…This scale’s version derives from the National Longitudinal Survey of Children and Youth (NLSCY; Statistics Canada, 2007 ). The data obtained in this national survey support the psychometric properties of the scale, with an adequate internal consistency ( α = .82) and correlations among items ranging from .38 to .64 ( Ferro & Boyle, 2013 ). For each item (e.g., “Overall, I have a lot to be proud of.”), the response scale ranged from 0 (false) to 4 (true) and the total score ranges from 0 to 16.…”

“…The general self-image subscale of SDQ has shown evidence of robust psychometric properties across adolescent populations, including those with chronic illness. 6,7 In this sample of adolescents, internal consistency of the SDQ-General self-image was good (α = .83). The Self-Perception Profile for Children (SPPC) was used to measure self-concept across the domains of scholastic competence, social competence, athletic competence, physical appearance, behavioral conduct, and global selfworth.…”

“…6 Though the natural course of self-concept is comparable across socioeconomic status, ethnicity, and nationality, 3 sex and health-related differences exist in the adolescent population (e.g., males report higher selfconcept compared to females across developmental periods) 3 and, individuals with chronic physical illnesses (e.g., asthma, diabetes, epilepsy) report lower self-concept (i.e., steeper declines in early adolescence and no rebound in late adolescence) compared to those without physical illness. 6,7 The negative association between physical illness and self-concept in adolescence is salient. First, the proportion of adolescents with physical illness represents a substantial portion of the population (>25%) with evidence suggesting that the prevalence is increasing, 8 suggesting that a growing segment of the population is at risk for poor self-concept.…”

“…Four models were established, that is, configural, metric, scalar and strict invariance, and gradually seek equivalence from loose to strict methods. The evaluation indicators for measurement invariance were as follows: ΔCFI < 0.010, ΔTLI < 0.010, and ΔRMSEA < 0.015 ( 43 , 44 ). Finally, according to Revelle and Zinbarg ( 45 ) argue that McDonald's omega in fact provides a more accurate approximation of a scale's reliability.…”
