Association Between the Parenting Competence and Quality of Life of Family Caregivers of Children Aged 0-3 Years: Cross-Sectional Study

Association Between the Parenting Competence and Quality of Life of Family Caregivers of Children Aged 0-3 Years: Cross-Sectional Study

The research hypothesizes a correlation between the Qo L and parenting ability, suggesting that enhancing parenting competence can alleviate parental stress and improve the Qo L. Recent studies on the Qo L of child caregivers focused on parents caring for children with special needs or intergenerational caregivers [9]. However, they overlooked the experiences of typical parental caregivers.

Assessing Social Interaction and Loneliness and Their Association With Frailty Among Older Adults With Subjective Cognitive Decline or Mild Cognitive Impairment: Ecological Momentary Assessment Approach

Assessing Social Interaction and Loneliness and Their Association With Frailty Among Older Adults With Subjective Cognitive Decline or Mild Cognitive Impairment: Ecological Momentary Assessment Approach

The K-IADL’s validation, conducted with older adults aged older than 65 years, demonstrated strong internal consistency (Cronbach α=0.94), high interrater reliability (κ value=0.81-0.95), and test-retest reliability correlation (≥ 0.70) [44]. In this study, high K-IADL scores indicated diminished functional capabilities and were analyzed as continuous variables.

Beliefs in Misinformation About COVID-19 and the Russian Invasion of Ukraine Are Linked: Evidence From a Nationally Representative Survey Study

Beliefs in Misinformation About COVID-19 and the Russian Invasion of Ukraine Are Linked: Evidence From a Nationally Representative Survey Study

Hypothesis 1: There is a correlation between BM-C and BM-U. The second aim was to examine associations between beliefs in the 2 sets of misinformation (BM-C and BM-U) and factors anecdotally observed or suggested in both contexts.

Impact of Demographic and Clinical Subgroups in Google Trends Data: Infodemiology Case Study on Asthma Hospitalizations

Impact of Demographic and Clinical Subgroups in Google Trends Data: Infodemiology Case Study on Asthma Hospitalizations

In a previous study by our team, we had (1) established a correlation between GT data related to common cold–related search terms and asthma hospitalizations and (2) evaluated whether GT data on the common cold, combined with data on admissions, could help forecast asthma hospitalizations.

Associations Between Sleep Duration and Activity of Daily Living Disability Among Older Adults in China: Cross-Sectional Study

Associations Between Sleep Duration and Activity of Daily Living Disability Among Older Adults in China: Cross-Sectional Study

To the best of our knowledge, the current study stands as one of the most extensive examinations of the correlation between sleep duration and ADL disability in the Chinese population. Compared to other countries, the prevalence rates of ADL disability among older adults were higher in China [39], with one study observing a rate as high as 41% [40]. In contrast, in America, the percentage of older adults aged 65‐74 years living with functional disability was 25.4% in 2015 [41].

Performance of a Digital Cognitive Assessment in Predicting Dementia Stages Delineated by the Dementia Severity Rating Scale: Retrospective Study

Performance of a Digital Cognitive Assessment in Predicting Dementia Stages Delineated by the Dementia Severity Rating Scale: Retrospective Study

The first goal of this study was to examine the correlation between scores obtained from the Brain Check standard battery of cognitive assessments (BC-Assess), a digital cognitive assessment, and scores obtained from the DSRS, a global staging scale. The second goal of this study is to evaluate the effectiveness of using the BC-Assess score to predict dementia stage delineated by the DSRS score.

Correlation Between Objective Habit Metrics and Objective Medication Adherence: Retrospective Study of 15,818 Participants From Clinical Studies

Correlation Between Objective Habit Metrics and Objective Medication Adherence: Retrospective Study of 15,818 Participants From Clinical Studies

Pairwise correlations between continuous variables were assessed using the Spearman rank correlation coefficient. Correlation coefficients were converted using Fisher Z-transformation to obtain CIs [25,26]. Correlation coefficients were compared by performing a z-test on the difference between their Fisher Z-transformations [26,27]. The proportion of variance in adherence explained by habit was quantified using the Pearson correlation coefficient, squared [26].

Digital Transformation of Rheumatology Care in Germany: Cross-Sectional National Survey

Digital Transformation of Rheumatology Care in Germany: Cross-Sectional National Survey

Data were analyzed using quantitative descriptive analysis and correlation analysis supported by SPSS (version 23.0; IBM). For correlation analyses, the data were converted into scores, and the Spearman rank correlation coefficient was calculated. The α error distribution was chosen to be 2-sided, as an undirected correlation is assumed to be open to hypotheses. These correlations had a correlation coefficient higher than 0.29.

Use of 4 Open-Ended Text Responses to Help Identify People at Risk of Gaming Disorder: Preregistered Development and Usability Study Using Natural Language Processing

Use of 4 Open-Ended Text Responses to Help Identify People at Risk of Gaming Disorder: Preregistered Development and Usability Study Using Natural Language Processing

For example, in a series of 7 studies, the Pearson correlation coefficients between estimates based on open responses (processed using the context-free latent semantic analysis model) and the actual scores for life satisfaction and harmony on life scales ranged between r=0.47 and r=0.72 [11].
