To qualify for the study, participants had to have a Barthel Index score of 60 or below, indicating substantial functional limitation, and no prior disability. Guided by stress–coping and social ecological perspectives, the researchers used latent profile analysis on seven indicators spanning illness appraisal, personal resources, affective burden, and perceived social context.

The analysis retained a four-profile solution. The largest group, 30.3 percent of participants, showed low strain with moderate resources. A further 27.6 percent combined low strain with high resources, while 25.2 percent fell into a high strain–low resources profile. The smallest group, 16.9 percent, reported high strain despite having high resources, a configuration showing that elevated strain can coexist with strong personal and social support.

Psychological adaptation was measured with the Psychological Adaptation Scale (PAS), and profile differences were tested using the Bolck–Croon–Hagenaars procedure. The high strain–low resources profile stood out clearly. Its members scored lower on PAS total and domain scores than every other profile after Holm adjustment, with adjusted total-score differences ranging from 16.6 to 21.6 points.

No statistically significant differences in adaptation emerged among the other three profiles. Older adults with high strain but high resources did not differ measurably from those with low strain and moderate or high resources, indicating that the combination of high strain and depleted resources, rather than strain alone, marked the profile most clearly linked to poorer current adaptation in this sample.

The researchers also explored which characteristics were associated with membership in particular profiles using R3STEP multinomial logistic regression. Functional status, sex, awareness of prognosis, income, and rural residence showed exploratory associations with selected profile contrasts.

Sensitivity analyses strengthened the central finding. The poorer adaptation of the high strain–low resources group persisted when an alternative three-profile solution was examined, and the pattern was broadly supported within the subgroup whose disability was cerebrovascular in origin.

The study’s cross-sectional design limits interpretation: profiles and adaptation were measured at the same time, so no causal direction can be established, and the hospital-based sample from one Chinese province may not generalize to all older adults with new-onset disability. The findings are also specific to people within the first three months after onset.

Even with those caveats, the authors conclude that the results may inform early rehabilitation assessment that considers emotional difficulties alongside personal and social resources, potentially helping identify the roughly one in four older patients whose combination of high psychological strain and few resources is most clearly associated with poorer current adaptation after disability begins.
