In stage three, all variables, except for visual status and PQOL, were considered for inclusion as independent variables in the equation used to conduct a standard multiple regression analysis that was run to determine the contribution they made both singly and collectively to the prediction of variance in PQOL.
Significant differences found on the remaining variables suggest that the visually impaired group is more likely to be single, in poorer health, less economically well off, less satisfied with their ability to perform activities of daily living, less mobile, less satisfied with their lives, and experiencing worse PQOL than the sighted group.
Follow-up analysis indicates that ordinal increases in loneliness were directly associated with significant decreases in economic well-being, mental health, satisfaction with activities of daily living, satisfaction with life, and PQOL.
STAGE 3: ASSESSING THE OVERALL IMPACT OF SOCIAL AND EMOTIONAL loneliness ON THE PQOL OF OLDER VISUALLY IMPAIRED adults
3) correlated with PQOL and that no independent variables were too highly correlated ([greater than or equal to] 0.
This group of participants was found to have more diagnosed health conditions and poorer physical and mental health, economic well-being, mobility, satisfaction with activities of daily living, satisfaction with life, and PQOL, and reported significantly higher rates of moderate and severe loneliness than their sighted counterparts.
Increasing levels of loneliness were found to be associated with large decreases in economic well-being, mental health, satisfaction with activities of daily living, satisfaction with life, and PQOL among those who were visually impaired.
Our findings that physical health, mental health, satisfaction with activities of daily living, and satisfaction with life made a unique and significant contribution to the PQOL of older visually impaired people confirms our earlier findings (La Grow, Alpass et al.
The unit weighted composite scores for the six PQOL indices and 21 dimensions of the Police Daily Hassles and Uplifts scales were used as multiple indicators [TABULAR DATA FOR TABLE 2 OMITTED] to estimate the latent constructs of Police Hassles, Police Uplifts, Operational Experiences, Psychological Distress and Well-Being.
Operational Experiences was not related to any of the PQOL, coping or personality constructs and, therefore, has not been shown in Fig.
More importantly, this finding demonstrates that causal antecedents should be taken into account when investigating the dimensionality of PQOL, since much of the correlation between positive and negative indicators is likely to be spurious, and thus mask the true underlying structure of PQOL.
