Spirituality, religion, social support and health among older Australian adults

AIM: To examine the impact of perceived importance of spirituality or religion (ISR) and religious service attendance (RSA) on health and well-being in older Australians. METHODS: A cross-sectional survey of 752 community-dwelling men and women aged 55-85 years from the Hunter Region, New South Wales. RESULTS: Overall, 51% of participants felt spirituality or religion was important in their lives and 24% attended religious services at least 2-3 times a month. In univariate regression analyses, ISR and RSA were associated with increased levels of social support (P < 0.001). However, ISR was also associated with more comorbidities (incidence-rate ratio= 1.2, 95% confidence interval 1.08-1.33). There were no statistically significant associations between ISR or RSA and other measures such as mental and physical health. CONCLUSION: Spirituality and religious involvement have a beneficial impact on older Australians' perceptions of social support, and may enable individuals to better cope with the presence of multiple comorbidities later in life.

On the validity of measuring change over time in routine clinical assessment: a close examination of item-level response shifts in psychosomatic inpatients

Objective: Significant life events such as severe health status changes or intensive medical treatment often trigger response shifts in individuals that may hamper the comparison of measurements over time. Drawing from the Oort model, this study aims at detecting response shift at the item level in psychosomatic inpatients and evaluating its impact on the validity of comparing repeated measurements. Study design and setting: Complete pretest and posttest data were available from 1188 patients who had filled out the ICD-10 Symptom Rating (ISR) scale at admission and discharge, on average 24 days after intake. Reconceptualization, reprioritization, and recalibration response shifts were explored applying tests of measurement invariance. In the item-level approach, all model parameters were constrained to be equal between pretest and posttest. If non-invariance was detected, these were linked to the different types of response shift. Results: When constraining across-occasion model parameters, model fit worsened as indicated by a significant Satorra–Bentler Chi-square difference test suggesting potential presence of response shifts. A close examination revealed presence of two types of response shift, i.e., (non)uniform recalibration and both higher- and lower-level reconceptualization response shifts leading to four model adjustments. Conclusions: Our analyses suggest that psychosomatic inpatients experienced some response shifts during their hospital stay. According to the hierarchy of measurement invariance, however, only one of the detected non-invariances is critical for unbiased mean comparisons over time, which did not have a substantial impact on estimating change. Hence, the use of the ISR can be recommended for outcomes assessment in clinical routine, as change score estimates do not seem hampered by response shift effects.
