The reliability and validity of the Life Satisfaction Index-A with survivors of traumatic brain injury

(1) Background: Self-reported measures play a crucial role in research, clinical practice, and health assessment. Instruments used to assess life satisfaction need validation to ensure that they measure what they are intended to detect true variations over time. An adapted instrument measuring life satisfaction for use among Ethiopian elders was lacking; therefore, this study aimed to culturally adapt and evaluate the psychometric properties of the Life Satisfaction Index for the Third Age—Short Form (LSITA-SF12) in Ethiopia. (2) Methods: Elderly people (n = 130) in Metropolitan cities of northwestern Ethiopia answered the LSITA-SF12 in the Amharic language. Selected reliability and validity tests were examined. (3) Result: The scale had an acceptable limit of content validity index, internal consistency, test-retest, inter-rater reliabilities, and concurrent and discriminant validities. (4) Conclusion: The Amharic language version of LSITA-SF12 appeared to be valid and reliable measures and can be recommended for use in research and clinical purposes among Amharic-speaking Ethiopian elders.

Life Satisfaction Index

The purpose of this study was to develop and evaluate the Adolescent Family Life Satisfaction Index. The self-report questionnaire was tested for internal consistency reliability. Tests for construct validity, concurrent validity, and internal consistency reliability provided support for the use of the over-all Adolescent Family Life Satisfaction Index, Parental Subscale, and Sibling Subscale for the measurement of adolescents' reports of satisfaction with family life.

Life Satisfaction Index

The Philadelphia Geriatric Center Morale Scale, Life Satisfaction Index, and Affect Balance Scale were translated into Castilian Spanish and Catalan. Responses to these scales were obtained by interviews with 151 elderly persons living in Spain. Reliability estimates for the Life Satisfaction Index and the Affect Balance subscales were comparable to those for English-speaking samples, while reliability estimates for the Philadelphia Geriatric Center Morale Scale were somewhat lower. Validity estimates among these scales were consistent with previous research and previously reported factor structures were found to fit the present data reasonably well, although factor loadings were lower than those previously reported. English and translated versions of the scales are provided in Appendix A.
