Latent Profile Analysis of General Self-Efficacy and Its Relationship with Quality of Life in Low Vision Patients
OBJECTIVE To explore the latent categories of general self-efficacy among low vision patients,investigate the relationship between different latent categories and quality of life,and identify factors influencing quality of life.METHODS A cross-sectional clinical study design was employed,involving 234 low vision patients(289 eyes)who were treated at Beijing Tongren Hospital,Capital Medical University,from May 2021 to April 2022.The General Self-Efficacy Scale(GSS)and the Chinese version of the Low Vision Quality of Life Scale(CLVQOL)were used for investigation.Mplus 8.0 and SPSS 26.0 statistical software were utilized to analyze the latent categories of general self-efficacy and their relationship with quality of life.Multiple linear regression was employed to analyze the factors influencing quality of life.RESULTS(1)Profile analysis results:When the number of latent profiles of general self-efficacy was three,the Akaike information criterion(AIC),Bayesian information criterion(BIC),and ajust Bayesian information criterion(aBIC)values were the highest,and entropy was closer to one,indicating that Profile three was the best model.(2)Category characteristics and naming:Low vision patients in this study were classified into three latent categories.Category one(23.9%)had the highest level of general self-efficacy and was named the High Efficacy Type.Category two(54.7%)scored at the intermediate level overall and was named the Moderate Efficacy Type.Category three(21.4%)had the lowest general self-efficacy scores and was named the Low Efficacy Type.(3)Basic characteristics of categories:Comparison of basic characteristics of low vision patients in different latent categories of general self-efficacy showed statistically significant differences in age(χ2=16.727,P=0.033),education level(χ2=11.389,P=0.023),source of medical expenses(χ2=27.914,P=0.000),household registration type(χ2=16.503,P=0.002),visual impairment Duration(χ2=36.607,P=0.000),occupation type(χ2=11.207,P=0.004),visual acuity(χ2= 19.433,P=0.001)and previous eye surgery(χ2=8.293,P=0.016),while other demographic differences were not statistically significant(P>0.05).(4)Relationship between categories and quality of life:The total scores of quality of life for low vision patients in different latent categories of general self-efficacy showed statistically significant differences(F=8.187,P=0.000).The comparison of quality of life dimensions showed statistically significant differences in far vision,mobility,light sensitivity(F=6.057,P=0.003),reading and fine work(F=9.648,P=0.000),adjustment ability(F=5.214,P=0.007),and daily life ability(F=8.164,P=0.000).(5)Multifactor analysis of factors influencing quality of life:Vision(t=-6.582,P=0.000),different latent categories of general self-efficacy(t=-2.092,P=0.039)showed statistically significant differences.CONCLUSIONS General self-efficacy among low vision patients exhibits heterogeneity.Special attention should be given to low efficacy individuals and patients with severe visual impairment,and strategies for general self-efficacy intervention should be explored to improve their quality of life.
