Comparing quality of life instruments: Sizing them up versus pediatric quality of life inventory and Kid-KINDL

Temporal associations between problematic use of the internet and self-stigma among people with substance use disorders: A cross-lagged model across one year

Self-stigma is a common experience for people with substance use disorders (SUDs). Understanding factors associated with self-stigma may aid in intervention development. This study investigated the reciprocal relationship between three types of problematic use of the internet [PUI; i.e. problematic use of social media (PUSM), problematic smartphone use (PSPU), and problematic gaming (PG)] and self-stigma among people with SUDs. This longitudinal study involved five waves of a survey given to individuals with SUDs in Taiwan. A total of 319 participants (85% male), with a mean age of 42.2 years (SD = 8.9), were recruited. The Smartphone Application-Based Addiction Scale, Bergen Social Media Addiction Scale, Internet Gaming Disorder-Short Form, and Self-Stigma Scale-Short Form were used. No significant associations between PUI and self-stigma were found in early waves (i.e., Waves 1 and 2). The earliest significant finding was identified between Wave 2 PSPU (smartphone) and Wave 3 self-stigma. Additionally, Wave 3 PSPU (smartphone) and PG (gaming) were associated with Wave 4 self-stigma, and Wave 4 PSPU (smartphone), PG (gaming), and PUSM (social media) were associated with Wave 5 self-stigma. Therefore, all three types of PUI (internet) may elevate self-stigma at different time points for individuals with SUDs. However, the reciprocal effects between self-stigma and PUI (internet) only occurred in PUSM (social media) at a later stage (i.e., from Wave 4 to Wave 5). In conclusion, people with SUDs who have PUI (internet) are at increased likelihood of developing more self-stigma, which may then increase subsequent PUSM (social media), forming a vicious cycle.

COVID-19: Sports activity and health-related quality of life of Swiss children and adolescents before and during the initial stay at home period

The aim of this study was to investigate sports activity and health-related quality of life (HRQoL) of Swiss children and adolescents (7–16 years) during the national COVID-19 stay at home (SaH) period. In total, 237 parent-child pairs gave information about HRQoL and sports activity (duration and type) before and during SaH. Results show that sports activity decreased during SaH and was also positively related to HRQoL. These findings indicate that sports activity of children and adolescents should be promoted during SaH, for which innovative home-based interventions may be useful.

Reciprocal Relationships Between Problematic Social Media Use, Problematic Gaming, and Psychological Distress Among University Students: A 9-Month Longitudinal Study

Background

The causal relationships between two specific types of problematic use in internet-related activities [i.e., problematic social media use (PSMU) and problematic gaming (PG)] and psychological distress remain controversial. The present study investigated the temporal relationships between PSMU, PG, and psychological distress (i.e., anxiety, depression) in university students.

Methods

Hong Kong and Taiwan university students [N = 645; n_male = 266; mean = 20.95 years (SD = 5.63)] were recruited for a survey study, with follow-ups at 3, 6, and 9 months after baseline assessment. The Bergen Social Media Addiction Scale, Internet Gaming Disorder Scale-Short Form, and the Hospital Anxiety and Depression Scale were used to assess studied variables. Demographics including age, physical characteristics (i.e., height, weight, and body mass index), and cigarette use were compared between participants who completed all the follow-ups and those who dropped out. Random intercept cross-lagged models were constructed to understand the reciprocal relationships between PSMU, PG, and psychological distress.

Results

No significant differences were found in age, physical characteristics, and cigarette use between participants who completed all the follow-ups and those who dropped out. Findings indicated that a high level of PSMU significantly increased the level of anxiety and a high level of anxiety significantly increased the level of PSMU. A high level of PSMU significantly increased the level of depression but the level of depression did not significantly affect the level of PSMU. A high level of PG significantly increased the level of anxiety, but the level of anxiety did not significantly affect the level of PG. A high level of depression significantly increased the level of PG, but the level of depression did not significantly affect the level of PG.

Conclusion

The patterns of the causal relationship between PIU and psychological distress variables differ. A reciprocal relationship was only found between the level of PSMU and the level of anxiety. Moreover, the longitudinal design found no differences in the waves in terms of gaming by the participants.

Weight Stigma Model on Quality of Life Among Children in Hong Kong: A Cross-Sectional Modeling Study

We proposed a model to examine the relationship among different types of weight-related stigmas and their relationship to quality of life (QoL). We recruited 430 dyads of elementary school children [mean age = 10.07 years; n_boy = 241 (56.0%); n_overweight = 138 (32.1%)] and their parents. Parents completed QoL instruments about their children assessing generic QoL and weight-related QoL. Children completed QoL instruments assessing generic QoL and weight-related QoL and stigma scales assessing experienced weight stigma, weight-related self-stigma, and perceived weight stigma. Experienced weight stigma was significantly associated with perceived weight stigma, and in turn, perceived weight stigma was significantly associated with weight-related self-stigma. However, experienced weight stigma was not directly associated with weight-related self-stigma. In addition, experienced stigma was negatively associated with both child-rated and parent-rated QoL. Perceived weight stigma was associated only with parent-rated weight-related QoL but not child-rated QoL. Self-stigma was associated with child-rated QoL but not parent-rated QoL. Moreover, perceived weight stigma and weight-related self-stigma were significant mediators in the association between body weight and children's QoL; experienced weight stigma was not a significant mediator. The study findings can be used to inform healthcare providers about the relationship among different types of stigmas and their influence on child-rated and parent-rated QoL and help them develop interventions to address the global trend of overweight/obesity in youth and pediatric populations.

Examination of the effects of technological device use on preschool children's quality of life: An exploratory and cross-sectional study

AIM

This exploratory and cross-sectional study aimed to evaluate the effects of technological device use on preschool children's life quality.

METHODS

One hundred twenty-five preschool students were recruited from two kindergartens affiliated to the Directorate of National Education in provincial centre of Zonguldak, Turkey. Personal Information Form and Quality of Life Scale for Young Children (KINDL Quality of Life Scale) were tools for data, collected by the researcher herself from parents through face-to-face interview method.

RESULTS

It was found in the study that 54.4% of the parents and 42.4% of their children who were involved in the study were frequently used technological devices. Mean score of the children's KINDL Quality of Life Scale was 79.2 (9.5; range 57-99). When comparing this score and its subscales with children's desire to not sleep due to playing virtual games and so forth, the differences between all the other subscales except self-esteem were significant (p < 0.05). A significant difference was also found between the children's sleeping hours and subscales such as self-esteem, physical and emotional health (p < 0.05).

CONCLUSION

The results show that more than half of the parents and their children frequently use the technological devices. Healthcare providers should inform the parents regarding the possibly negative consequences such as negatively affecting the children's quality of life.

Assessing whether child and parent reports of the KINDL questionnaire measure the same constructs of quality of life in children with attention-deficit hyperactivity disorder

Background

Discrepancy between child self-report and parent proxy-report has long been documented in the health-related quality of life (HRQoL) measurement of children with chronic health conditions. This study aims to assess whether child and parent reports of the Kinder Lebensqualität fragebogen (KINDL) questionnaire measure the same construct of HRQoL in children with attention-deficit hyperactivity disorders (ADHD).

Methods

Participants were 122 Iranian children with ADHD and 127 of their parents, who completed the child and parent reports of the KINDL, respectively. Internal consistency of the child and parent reports were assessed by Cronbach's alpha. The intra-class correlation (ICC) coefficient and factor analysis were applied to assess whether the child self-report and the parent proxy-report measured the same construct of HRQoL. Additionally, convergent and discriminant validity were assessed using the Spearman correlation.

Results

The results of factor analysis revealed that the child self-report and parent proxy-report measure two different aspects of HRQoL. Moreover, both versions of the KINDL instrument showed excellent convergent and discriminant validity. The internal consistency was close to or greater than 0.7 for all domains of both child and parent reports.

Conclusions

Although the child self-report and the parent proxy-report of the Persian version of the KINDL have good psychometric properties, they are not interchangeable. This finding indicates that Iranian children with ADHD and their parents evaluate children's HRQoL from their own viewpoints.

Can We Apply WHOQOL-AGE to Asian Population? Verifying Its Factor Structure and Psychometric Properties in a Convenience Sample From Taiwan

Objectives: To translate and validate a recently developed quality of life instrument (WHOQOL-AGE) on geriatric population into Chinese.

Method: Using cross-sectional observational design, the WHOQOL-AGE was conducted among older people through interview. Confirmatory factor analysis (CFA) was used to examine the factor structure and multigroup CFA used to examine the measurement invariance.

Results: Through convenience sampling, 522 older adults (mean age = 73.42) participated in the study. Among them, 194 were males, 213 had an educational level at primary school or below, 398 were residing in the community, and 307 were aged 70 years or above. A bifactor structure (items Q1–Q8 are embedded in the factor 1; items Q9–Q13 embedded in the factor 2; and all the items embedded in an additional construct of QoL) was confirmed by the CFA in both the entire sample (χ² = 25.4; df = 51; p = 0.999) and the subgroup sample with age 70 years or above (χ² = 25.28; df = 51; p = 1.000). Multigroup CFAs results supported the measurement invariance for the WHOQOL-AGE across genders, having different educational levels, living in different settings and age groups. It also shows good known-groups validity.

Conclusions: The promising psychometric properties of the WHOQOL-AGE were found in our convenience sample of older Taiwanese. The supported measurement invariance indicates that the older people in different conditions of gender, educational level, and living setting interpret the WHOQOL-AGE similarly. However, our results should be interpreted with cautious because of the sample representativeness.

Psychological distress and quality of life in Iranian adolescents with overweight/obesity: mediating roles of weight bias internalization and insomnia

PURPOSE

To examine whether weight-related self-stigma (aka weight bias internalization) and insomnia are potential predictors of psychological distress and quality of life (QoL) among Iranian adolescents with overweight (OW)/obesity (OB). To examine whether weight-related self-stigma and insomnia are potential mediators in the relationship between excess weight and health outcomes of distress and QoL.

METHODS

All participants (n = 934; 444 males; mean age = 15.7 ± 1.2 years; zBMI = 2.8 ± 1.0) completed questionnaires on weight-related self-stigma and insomnia at baseline. Six months later, they completed questionnaires on psychological distress and QoL to assess health outcomes. Relationships among variables were tested using mediation analyses with bootstrapping method.

RESULTS

Weight-related self-stigma significantly mediated the effects of zBMI on psychological distress (effect = 0.22; bootstrapping SE = 0.09; 95% CI = 0.08, 0.45), psychosocial QoL (effect = - 0.64; bootstrapping SE = 0.19; 95% CI = - 1.10, - 0.32), and physical QoL (effect = - 1.35; bootstrapping SE = 0.54; 95% CI = - 2.43, - 0.26). Insomnia also significantly mediated the effects of zBMI on psychological distress (effect = 2.18; bootstrapping SE = 0.31; 95% CI = 1.61, 2.81), psychosocial QoL (effect = - 0.89; bootstrapping SE = 0.33; 95% CI = - 1.60, - 0.28), and physical QoL (effect = - 0.83; bootstrapping SE = 0.42; 95% CI = - 1.69, - 0.02). Full mediations were found in psychosocial QoL; partial mediations were found in psychological distress and physical QoL.

CONCLUSIONS

Weight-related self-stigma and insomnia were significant mediators in the effects of excess weight on health outcomes. Therefore, it is important to identify and treat weight-related self-stigma and insomnia for adolescents with OW/OB.

Psychometric testing on two weight stigma instruments in Iran: Weight Self-Stigma Questionnaire and Weight Bias Internalized Scale

PURPOSE

This study aimed to comprehensively and thoroughly examine the psychometric properties of two commonly used weight-related self-stigma instruments on Iranian adolescents with overweight or obesity: Weight Self-Stigma Questionnaire [WSSQ] and Weight Bias Internalization Scale [WBIS].

METHODS

After ensuring the linguistic validity of both the WSSQ and WBIS in their Persian versions, 737 Iranian adolescents with overweight or obesity (male = 354; mean age = 15.8 ± 1.3 years; body mass index = 30.0 ± 4.8 kg/m²) completed both questionnaires and other relevant measures regarding their depression, anxiety, stress, dietary self-efficacy, weight efficacy lifestyle, quality of life, body fat, self-esteem, body shape preoccupation, and sleepiness.

RESULTS

In the scale level, the confirmatory factory analysis verified the two-factor structure for the WSSQ and the single-factor structure for the WBIS. The factorial structures were further found to be invariant across gender (male vs. female) and across weight status (overweight vs. obesity). Additionally, both the WSSQ and WBIS had promising properties in internal consistency, test-retest reliability, separation reliability, and separation index. In the item level, all items but WBIS item 1 (infit mean square = 1.68; outfit mean square = 1.60) had satisfactory properties in factor loadings, corrected item-total correlation, test-retest reliability, and infit and outfit mean square. Moreover, all the items did not display substantial differential item functioning (DIF) across gender and across weight status.

CONCLUSION

Both the WSSQ and WBIS were valid instruments to assess the internalization of weight bias for Iranian adolescents with overweight or obesity.

The Mediating Effects of Eating Disorder, Food Addiction, and Insomnia in the Association between Psychological Distress and Being Overweight among Iranian Adolescents

With obesity and excess weight remaining a serious concern worldwide, investigating the mechanisms underlying this is of great importance. Psychological distress is a possible trigger contributing to excess weight for adolescents. Moreover, the association between psychological distress and excess weight may be mediated by eating disorder, food addiction, and insomnia. The present study utilized parallel mediation analysis to assess the aforementioned associations and possible mediation effects among Iranian adolescents. Through stratified and clustered sampling, adolescents (N = 861; mean ± SD age = 15.9 ± 3.2; 372 males) participated and were followed for a one-year period. Excess weight (standardized body mass index, z-BMI); psychological distress (Depression, Anxiety, and Stress Scale-21); eating disorder attitudes (Eating Attitude Test-26); food addiction (Yale Food Addiction Scale for Children); and insomnia (Insomnia Severity Index) were assessed. Eating disorder attitudes, food addiction, and insomnia were significant mediators in the association of psychological distress and z-BMI. Additionally, psychological distress had direct effects on z-BMI. Given that eating disorder attitudes, food addiction, and insomnia showed mediated effects in the temporal association of psychological distress and excess weight, healthcare providers are encouraged to design programs on improving these three mediators to help adolescents overcome excess weight problems.

Mediated effects of eating disturbances in the association of perceived weight stigma and emotional distress

PURPOSE

This study aimed to examine the relationships between perceived weight stigma, eating disturbances, and emotional distress across individuals with different self-perceived weight status.

METHODS

University students from Hong Kong (n = 400) and Taiwan (n = 307) participated in this study and completed several questionnaires: Perceived Weight Stigma questionnaire; Three-factor Eating Questionnaire; Hospital Anxiety and Depression Scale. Each participant self-reported their height, weight, and self-perceived weight status.

RESULTS

After controlling for demographics, perceived weight stigma was associated with eating disturbances (β = 0.223, p < 0.001), depression (β = 0.143, p < 0.001), and anxiety (β = 0.193, p < 0.001); and eating disturbances was associated with depression (β = 0.147, p < 0.001) and anxiety (β = 0.300, p < 0.001) in the whole sample. Additionally, eating disturbances mediated the association between perceived weight stigma and emotional distress. Similar findings were shown in the subsamples who perceived themselves as higher weight or normal weight and in the male and female subsamples. However, in the subsamples who perceived themselves as lower weight, only the links between eating disturbances and emotional distress were significant.

CONCLUSION

Perceived weight stigma was associated with eating disturbances and emotional distress in young adults with both higher and normal weight. Eating disturbances were associated with emotional distress regardless of participants' weight status.

Using extended theory of planned behavior to determine factors associated with help-seeking behavior of sexual problems in women with heart failure: a longitudinal study

Introduction: This study used extended theory of planned behavior (extended TPB) to understand the underlying factors related to help-seeking behavior for sexual problems among Iranian women with heart failure (HF).Methods: We recruited 758 women (mean age = 61.21 ± 8.92) with HF at three university-affiliated heart centers in Iran. Attitude, subjective norms, perceived behavioral control, behavioral intention, self-stigma of seeking help, perceived barriers, frequency of planning, help-seeking behavior, and sexual function were assessed at baseline. Sexual function was assessed again after 18 months. Structural equation modeling was used to explain change in sexual functioning after 18 months.Results: Attitude and perceived behavioral control were positively correlated to behavioral intention. Behavioral intention was negatively and self-stigma in seeking help was positively correlated to perceived barriers. Behavioral intention was positively and self-stigma in seeking help was negatively correlated to frequency of planning. Perceived behavioral control, behavior intention, and frequency of planning were positively and self-stigma in seeking help and perceived barriers were negatively correlated to help-seeking behavior. Help-seeking behavior was positive correlated to the change of FSFI latent score.Conclusions: The extended TPB could be used by healthcare professionals to design an appropriate program to treat sexual dysfunction in women with HF.

Time invariance of three ultra-brief internet-related instruments: Smartphone Application-Based Addiction Scale (SABAS), Bergen Social Media Addiction Scale (BSMAS), and the nine-item Internet Gaming Disorder Scale- Short Form (IGDS-SF9) (Study Part B)

Given the many technological advances over the past two decades, a small minority of young people are at risk of problematic use or becoming addicted to these technologies (including activities on the internet and smartphones). Many brief psychometric scales have been developed to assess those at risk of problematic use or addiction including the six-item Smartphone Application-Based Addiction Scale [SABAS], the six-item Bergen Social Media Addiction Scale [BSMAS], and the nine-item Internet Gaming Disorder Scale-Short Form [IGDS-SF9]). However, to date, the reproducibility of these three scales has only been examined over a short period of time (e.g., two weeks), and it is unclear whether they are time invariant across a longer period (e.g., three months). Given the emergence of internet and smartphone addiction in Chinese population, the present study translated the three instruments into Chinese and recruited 640 university students (304 from Hong Kong [99 males] and 336 from Taiwan [167 males]) to complete the three scales twice (baseline and three months after baseline). Multigroup confirmatory factor analysis (MGCFA) was applied to examine the time invariance. The intraclass correlation coefficient (ICC) was used to assess the relative reliability, and the percentage of smallest real difference (SRD%) was utilized to explore the absolute reliability for the three scales. MGCFA showed that all three scales were time invariant across three months. ICC demonstrated that all the scales were satisfactory in reproducibility (0.82 to 0.94), and SRD% indicated that all the scales had acceptable measurement noise (23.8 to 29.4). In conclusion, the short, valid, reliable, and easy-to-use Chinese SABAS, BSMAS, and IGDS-SF9 show good properties across periods of three months.

The Predictive Relationship of Health Related Quality of Life on Objectively-Measured Sleep in Children: A Comparison Across BMI Ranges

Sleep is considered a major factor related to children's general quality of life with regards to their health outcomes, general well-being, and daily life functions. Kid-KINDL, a health-related quality of life (HRQOL) measure, was used in a consecutive 12-week longitudinal study to compare the association between children's quality of life (QoL) and sleep duration across different BMI ranges. To reduce recall bias, each child wore an electronic pedometer on their wrist to record their sleep duration. The Pearson χ2 test, one-way analysis of variance (ANOVA), and mixed effect repeated measures analysis was used to investigate the association between children's QoL and their sleep duration. The original QoL scores showed that underweight children had lower emotional, family relationship, friendship, and school-related scores, and that overweight children had lower physical satisfaction and self-esteem scores. Emotional (beta = -0.3, p < 0.01) and family relationships (beta = 0.20, p = 0.01) significantly influenced the sleep duration of underweight children. The score of emotional well-being decreased by 0.3, while sleep duration increased by an hour. The poorer the emotional well-being of children, the longer they slept. The score of family well-being increased by 0.2, while sleep duration increased by an hour. The better family quality children had, the longer they slept; For overweight children, the score of family well-being increased by 0.08, while sleep duration increased by an hour (beta = 0.08, p = 0.04). Their sleep got longer when they had better family quality. Physical and school satisfaction scores also significantly affected the sleep duration of obese children. When the score of physical and school increased by 0.09, the sleep duration increases by an hour (beta = 0.09, p = 0.01; beta = 0.09, p < 0.01, respectively). The better the quality of physical condition and school life was, the longer sleep they would get. This study might be the first longitudinal study to evaluate the relationship between QoL and sleep duration, using an objective device but subjective questionnaires, across BMI ranges in a pediatric population.

Investigating the Relationship Between Weight-Related Self-Stigma and Mental Health for Overweight/Obese Children in Hong Kong

This study aimed to test the differences of weight-related self-stigma and mental health conditions between overweight (OW) and non-OW children in Hong Kong. The correlations between weight-related self-stigma and mental health conditions were also investigated. Children aged 8 to 12 years (n = 367; 198 boys) completed questionnaires on weight-related self-stigma (Weight Bias Internalization Scale [WBIS] and Weight Self-Stigma Questionnaire [WSSQ]) and mental health conditions (Brief Symptom Rating Scale-5 [BSRS-5]). Compared with non-OW children (n = 241; 143 boys), OW children (n = 114; 55 boys) had higher weight-related self-stigma in the WBIS (26.49 ± 8.68 vs. 21.58 ± 7.54; p < 0.001) and WSSQ scores (26.36 ± 8.98 vs. 21.91 ± 8.71; p < 0.001). No significant difference was found between OW and non-OW children in mental health conditions as reflected by the BSRS-5 score (4.29 ± 4.35 vs. 4.44 ± 4.16; p = 0.761). BSRS-5 was significantly associated with the WBIS. OW children tended to have a higher level of self-stigma; those having a higher level of weight-related self-stigma presented with more mental health problems.

Negative Impacts of Self-Stigma on the Quality of Life of Patients in Methadone Maintenance Treatment: The Mediated Roles of Psychological Distress and Social Functioning

A sample of heroin users (n = 250) in methadone maintenance treatment (MMT) was used in this cross-sectional study to clarify the mechanisms of the effects of stigma on quality of life (QoL) through psychological distress and social functioning. All the participants had their self-stigma, psychological distress, social functioning, and QoL measured. Psychological distress and social functioning were proposed to be mediators between self-stigma and QoL. Several linear models using structural equation modeling were conducted to examine the mediated effects. The negative effects of self-stigma on QoL were significantly mediated by psychological distress, as self-stigma directly and significantly influenced psychological distress, but not social functioning. This study demonstrated a linear model describing the effects of self-stigma on QoL for opioid-dependent individuals; psychological distress was also an important mediator between self-stigma and their QoL. Clinicians were able to notice the importance of reducing self-stigma for opioid-dependent individuals according to the following results: higher levels of self-stigma were associated with high psychological distress, decreased social functioning, and impaired QoL. Our mediation findings suggest that treating psychological distress is better than treating social functioning if we want to eliminate the effects of self-stigma on QoL for heroin users.
