Problematic smartphone use and academic achievement: A systematic review and meta-analysis.

Background and aims: The present study aimed to synthesize existing quantitative evidence on the relationship between problematic smartphone use (PSU) and academic achievement with a focus on quantifying its magnitude and examining its potential moderators. Methods: Eligible studies were searched for up to February 10, 2023 in six different databases (i.e., MEDLINE, Current Contents Connect, PsycINFO, Web of Science, SciELO, and Dissertations & Theses Global). Studies were considered eligible if they provided information derived from self-report instruments that allowed statistical calculation of the relationship between PSU and academic achievement. Pooled effect sizes (r) were computed using a random-effects model. Meta-regressions were conducted to test the influence of study-level moderators on the relationship of interest. Influence analyses and a three-parameter selection model (3PSM) were conducted to examine the robustness of the results and publication bias, respectively. Results: A total of 33 effect sizes from 29 studies (n = 48,490) were retrieved. Results showed a small effect size (r = -0.110), which tended to be larger in samples consisting of students from elementary and middle schools. Discussion and Conclusions: Findings from the present study contribute to the understanding of a potential determinant of decreased academic achievement by providing evidence that PSU may be one of them.

Psychological wellbeing in teachers. Study in teachers of early childhood and primary education.

Recently, there has been a growing interest in emotional wellbeing, even from the early stages of education. In order to work wellbeing among the students it is essential to analyze the wellbeing of the teachers who are teaching and working with the children. This study examines psychological wellbeing in early childhood (0-6 years) and primary school teachers (6-12 years). The study comprised 236 early childhood and primary school teachers - 76 men (32.2%) and 160 women (67.8%) - with ages ranging from 25 to 61 years (average 37.69 years - s.d.=2.47). The study examined psychological wellbeing (happiness, eudemonic wellbeing, self-esteem, and life satisfaction) and several sociodemographic variables (gender, age, years in the job, type of contract, and educational stage). Participants answered an ad-hoc sociodemographic questionnaire and subjective happiness, eudemonic wellbeing, self-esteem, and life satisfaction standard questionnaires. Early childhood schoolteachers yielded higher wellbeing-related scores. All the wellbeing-related variables were found to be correlated with one another, except for happiness and self-esteem. Teachers working in different educational stages were found to yield significantly different wellbeing-related scores. For the first time, network analysis revealed differences in the associations of the variables under study among Early Childhood Education and Primary Education teachers. Thus, while happiness and satisfaction with life were found to be correlated in both groups, stronger correlations between self-esteem and eudaimonic wellbeing were found in early childhood education teachers, while in primary education teachers the correlation was with satisfaction with life, which indicates that early childhood teachers present greater spiritual and existential understanding, leading to eudaimonic wellbeing. These differences between educational stages are considered greatly significant. It was concluded that more research is needed, ideally with broader and longitudinal studies, to understand and describe the relationship between personal and even structural variables and wellbeing.

Effects of Pubertal Timing and Pubertal Tempo on Social Physique Anxiety, Self-determined Motivation, and Exercise in Early Adolescent Girls.

PURPOSE: Research has shown that there is a decrease in physical activity levels during early adolescence, especially for girls. Previous studies have shown that the social physique anxiety (SPA) may be a controlling factor influencing exercise motivation and engagement in this behavior; however, the potential role that puberty plays in this decrease has not been considered until now. The objective of the present study was to examine the impact of pubertal timing and pubertal tempo on SPA and exercise motivation and behavior. METHODS: Data from 328 early adolescent girls, aged between 9 and 12 at the time of joining the study, were collected in 3 waves over a 2-year period. Using structural equation modeling techniques, different 3-time-point growth models were estimated to examine if earlier maturing and compressed maturing in girls had differential effects on SPA and exercise motivation and behavior. RESULTS: The results from growth analyses suggest that early maturing (according to all the pubertal indicators considered, except menstruation) tends to translate into (1) an increase in SPA levels and (2) a decrease in exercise - in the latter case, by reducing self-determined motivation. However, no differential effects from any of the pubertal indicators were found for compressed maturing in girls. DISCUSSION: These results highlight the need for increased efforts toward developing programs aimed at helping early maturing girls to cope with the challenges of puberty with a particular focus on SPA experiences and exercise motivation and behavior.

Social physical anxiety and eating disorders: A systematic review and meta-analysis.

The present study's aim was to summarize existing quantitative evidence linking social physique anxiety (SPA) and eating disorders (ED). Eligible studies were searched for up to June 2, 2022 in six databases: MEDLINE, Current Contents Connect, PsycINFO, Web of Science, SciELO, and Dissertations & Theses Global. Studies were considered eligible if they included information derived from self-report instruments that allowed for computing the relationship between SPA and ED. Pooled effect sizes (r) were computed using three-level meta-analytic models. Potential sources of heterogeneity were examined using univariable and multivariable meta-regressions. Influence analyses and a three-parameter selection model (3PSM) were used for the purpose of examining the robustness of the results and publication bias, respectively. Results summarizing 170 effect sizes from 69 studies (N = 41,257) showed two main groups of findings. Firstly, that SPA and ED were very largely related (i.e., r = .51). Secondly, that this relationship was stronger (i) among individuals from Western countries, and (ii) when ED scores concerned the diagnostic feature of bulimia/anorexia nervosa involving body image disturbances. The present study adds to the current understanding of ED by suggesting that SPA is a maladaptive emotion with a potential role in the onset and maintenance of these group of pathologies.

Psychometric Examination of the Body, Eating, and Exercise Comparison Orientation Measure (BEECOM) among Spanish Adolescents and Young Adults.

The Body, Eating, and Exercise Comparison Orientation Measure (BEECOM) has been frequently used within the context of research on eating disorders (ED). Although both long (BEECOM-L) and short (BEECOM-S) versions of the instrument exist, their psychometric properties have not yet been concurrently investigated across different populations in terms of age and gender. The present study aimed to compare the psychometric properties of both the BEECOM-L and the BEECOM-S among Spanish male and female non-clinical adolescents and young adults. Data from 4 samples including 1213 middle school and college students enrolled in 10 education centers from southern Spain (age ranging from 12 to 35 years, Mage = 17.796, SDage = 4.796, 53% females) were analyzed using factorial, correlation, and regression analysis techniques. Results provided evidence that support the reliability, measurement invariance according to age and gender, and convergent/incremental validity for the scores from both the BEECOM-L and BEECOM-S. Concerning factorial validity, marginally acceptable and adequate goodness-of-fit indices were obtained for the BEECOM-L and BEECOM-S, respectively. The BEECOM-S proves to be a psychometrically sound instrument with potential value for assessing social comparisons focused on body, eating, and exercise in non-clinical adolescents and young adults from Spain.

A Review of the Components of Problematic Exercise in Psychometric Assessment Instruments.

Backgrounds: The range of theoretical conceptualizations of problematic exercise in psychometric assessment instruments makes it difficult to identify the components that define this phenomenon. A better understanding of the underlying components of problematic exercise may contribute to progress toward providing scientific evidence that allows for deciding whether problematic exercise should be considered a substantive mental health disorder. The objective of the present review was to examine and compare, through a content analysis of their items, the components of problematic exercise in psychometric assessment instruments identified in a recent systematic review. Methods: A total of 33 components of problematic exercise were identified in the 17 assessment instruments included in the present review. Results: The results show that, despite the lack of consensus in the operational definition of their factors and the variety of ways of wording their items, the instruments reflect some common components that might indicate core criteria (i.e., salience, withdrawal, and mood modification) or candidate components (i.e., conflict, and continuance despite problems) of problematic exercise. However, other components of different nature were shown to be specific to some of the problematic exercise conceptualizations on which the assessment instruments are based. Conclusion: In the interest of reaching a consensus that allows to advance in this research field, further studies are needed to resolve which components are inherently problematic.

Examining the reliability of the scores of self-report instruments assessing problematic exercise: A systematic review and meta-analysis.

Background and aims: Problematic exercise (PE) has mainly been assessed with self-report instruments. However, summarized evidence on the reliability of the scores derived from such instruments has yet to be provided. The present study reports a reliability generalization meta-analysis of six well-known self-report measures of PE (Commitment to Exercise Scale, Compulsive Exercise Test, Exercise Addiction Inventory, Exercise Dependence Questionnaire, Exercise Dependence Scale, and Obligatory Exercise Questionnaire). Methods: Pooled effect sizes were computed using a random-effect model employing a restricted maximum likelihood estimation method. Univariable and multivariable meta-regressions analyses were employed for testing moderator variables. Results: Data retrieved from 255 studies (741 independent samples, N = 254,174) identified three main groups of findings: (i) pooled alpha values that, ranging from 0.768 to 0.930 for global scores and from 0.615 to 0.907 for subscale scores, were found to be sensitive to sociodemographic and methodological characteristics; (ii) reliability induction rates of 47.58%; and (iii) the virtually non-existent testing of the assumptions required for the proper applicability of alpha. Data unavailability prevented the provision of summarized reliability estimates in terms of temporal stability. Discussion: These findings highlight the need to improve reliability reporting of the scores of self-reported instruments of PE in primary studies. This implies providing both prior justification for the appropriateness of the index employed and reliability data for all the subpopulation of interest. The values presented could be used as a reference both for comparisons with those obtained in future primary studies and for correcting measurement-related artefacts in quantitative meta-analytic research concerning PE.

Internalization of body shape ideals and body dissatisfaction: A systematic review and meta-analysis.

OBJECTIVE: The present meta-analysis summarizes existing evidence on the relationship between the internalization of body shape ideals (IBSI) and body dissatisfaction. METHOD: Pooled effect sizes (r) were computed using a random-effects model. The robustness of the results was examined using influence analyses. Potential predictors of effect heterogeneity were examined using subgroup analysis and univariable/multivariable meta-regressions. Publication bias was examined using the three-parameter selection model (3PSM). RESULTS: A total of 141 effect-sizes from 78 studies (N = 39,491) were retrieved. Results revealed medium (r = .25; muscular/athletic-ideal internalization) to very large (r = .43, general attractiveness-ideal internalization; and r = .45, thin-ideal internalization) relationships, all these being largely similar in male and female individuals. DISCUSSION: IBSI and body dissatisfaction were strongly linked: (a) in younger individuals (general attractiveness-ideal internalization); (b) when IBSI was operationalized in terms of endorsement rather than mere awareness of appearance ideals; (c) in studies of lower methodological quality (muscular/athletic-ideal internalization); and (d) when IBSI was assessed using instruments involving social comparisons. Given the largely cross-sectional nature of data included in this meta-analysis, further testing in prospective and experimental studies is needed to confirm hypotheses about causality of observed associations. Such findings would have impact for prevention and intervention studies.

OBJETIVO: El presente metanálisis resume la evidencia existente sobre la relación entre la internalización de los ideales de la figura corporal (IBSI) y la insatisfacción corporal. MÉTODO: Los tamaños de los efectos agrupados (r) se calcularon utilizando un modelo de efectos aleatorios. La robustez de los resultados se examinó mediante análisis de influencia. Los predictores potenciales de heterogeneidad del efecto se examinaron mediante análisis de subgrupos y metarregresión univariable/multivariable. El sesgo de publicación se examinó mediante la inspección visual de la simetría de la gráfica de embudo y la prueba de Egger. RESULTADOS: Se recuperó un total de 141 tamaños de efectos de 78 estudios (N = 39 491). Los resultados revelaron relaciones medias (r = .25; internalización muscular/atlética-ideal) a relaciones muy grandes (r = .43, internalización ideal de atractivo general; y r = .45, internalización delgada-ideal), siendo todas ellas en gran parte similares en individuos masculinos y femeninos. DISCUSIÓN: La Internalización de los Ideales de la Figura Ideal (IBSI) y la insatisfacción corporal fueron ligados fuertemente: (i) en individuos más jovenes (internalización atractivo-ideal general); (ii) cuando IBSI se puso en marcha en términos de aprobación en lugar de la mera conciencia de los ideales de apariencia; (iii) en estudios de menor calidad metodológica (internalización muscular/atlética-ideal); y (iv) cuando IBSI fue evaluado utilizando instrumentos que implican comparaciones sociales. Dada la gran naturaleza transversal de los datos incluidos en este metanálisis, se necesitan pruebas adicionales en estudios prospectivos y experimentales para confirmar hipótesis sobre la causalidad de las asociaciones observadas. Tales hallazgos tendrían impacto para los estudios de prevención e intervención.

Theoretical conceptualisations of problematic exercise in psychometric assessment instruments: A systematic review.

BACKGROUND AND AIMS: The aim of the present systematic review was to identify psychometric tools developed to assess problematic exercise in order to identify and compare their theoretical conceptualisations on which they are based. METHODS: A systematic literature search was conducted in the electronic databases Web of Science, Scielo, PsychINFO, PsycTEST and SCOPUS from their inception to January 2020. RESULTS: Seventeen assessment instruments met the eligibility criteria to be included in the present review. The instruments were classified according to their conceptualisation into five groups: (i) problematic exercise as an end of an exercise continuum, (ii) problematic exercise as a means of regulating body size and weight, (iii) problematic exercise as dependence, (iv) problematic exercise as a behavioural addiction and (v) no clear conceptualisation. DISCUSSION: The results suggest that the conceptualisations of the assessment instruments have resulted in a strong dichotomy in relation to the primary or secondary character of the problematic exercise that might be limiting the capacity of the instruments to adequately capture the multidimensionality of this construct. CONCLUSIONS: Given the interest in understanding the complexity surrounding the problematic exercise, future research should develop more comprehensive definitions of this construct. This would allow a greater conceptual consensus to be reached that would allow progress to be made in the study of the problematic exercise.

A Systematic Review and Meta-Analysis on the Relationship between Body Dissatisfaction and Morbid Exercise Behaviour.

BACKGROUND: The present study aimed to quantify the relationship between body dissatisfaction and morbid exercise behaviour (MEB). METHODS: The electronic databases MEDLINE, PsycINFO, Web of Science, SciELO, and Dissertations & Theses Global were searched from inception to September 2020. Pooled effect sizes corrected for sampling errors (r+) were computed using a bare-bones meta-analysis. The robustness of the results was examined by influence analyses. The presence of moderators was examined by inspection of the variance in r+ attributable to sampling errors and 80% credibility intervals, followed by subgroup analysis and univariable/multivariable meta-regressions. Publication bias was examined by visual inspection of funnel plot symmetry, cumulative meta-analysis, and Egger's test. RESULTS: A total of 41 effect sizes from 33 studies (n = 8747) were retrieved. Results showed a significant and near to moderate effect size (r+ = 0.267, 95% CI = 0.226 to 0.307), and this did not differ by gender, BMI, age, percentage of Whites, study quality, or MEB measure. Conversely, effect sizes were found to be stronger in published and more recently conducted studies. CONCLUSION: The findings indicate that body dissatisfaction is one of the likely causes underlying MEB. This suggests the need for further longitudinal research aimed at confirming the potential causal nature of this relationship.

Morbid exercise behaviour and eating disorders: A meta-analysis.

BACKGROUND AND AIMS: This study examined the relationship between self-reported symptoms of morbid exercise behaviour (MEB) and eating disorders (ED) using meta-analytic techniques. METHODS: We systematically searched MEDLINE, PsycINFO, Web of Science, SciELO and Scopus. Random effects models were used to compute pooled effect sizes estimates (r). The robustness of the summarized estimates was examined through sensitivity analyses by removing studies one at a time. RESULTS: Sixty-six studies comprising 135 effect-sizes (N = 21,816) were included. The results revealed: (a) small-sized relationship in the case of bulimic symptoms (r = 0.19), (b) small- (r = 0.28) to medium-sized relationships (r = 0.41) in the case of body/eating concerns, and (c) medium-sized relationships in the case of overall ED symptoms (r = 0.35) and dietary restraint (r = 0.42). Larger effect sizes were observed in the case of overall ED symptoms in clinical, younger, and thinner populations, as well as when employing a continuously-scored instrument for assessing ED or the Compulsive Exercise Test for assessing MEB. Larger effect sizes were also found in female samples when the ED outcome was dietary restraint. CONCLUSIONS: The identified gaps in the literature suggest that future research on the topic may benefit from: (a) considering a range of clinical (in terms of diagnosed ED) and non-clinical populations from diverse exercise modalities, (b) addressing a wide range of ED symptomatology, and (c) employing longitudinal designs that clarify the temporal direction of the relationship under consideration.

Examining the role of social physique anxiety on the relationship between physical appearance comparisons and disordered eating symptoms among Spanish emerging adults.

The present study extends previous research by examining the moderating/mediating role of social physique anxiety (SPA) on the relationship between physical appearance comparisons (PAC) and symptoms of disordered eating (DE) in adolescent population. A total of 555 emerging adults (59% women) ranging from 18 to 30 years of age (M = 21.34, SD = 2.80) were recruited from two public universities from Spain using a non-probabilistic sampling technique. Participants completed a self-reported questionnaire comprising the variables of research interest. Once the effects of sex (i.e., being men or women), age, body mass index, and depressive symptoms were controlled for, the results from bootstrapping cross-sectional regression analyses supported both the moderating and mediating effect of SPA on the relationship between PAC and DE. Sex did not moderate any of these relationships. From these findings, it follows that incorporating strategies aimed at decreasing PAC and SPA may contribute to improved prevention efforts aimed at decreasing DE among Spanish emerging adults of both sexes.

Fitness-Related Self-Conscious Emotions and Risk for Exercise Addiction: Examining the Mediating Role of Passion.

Fitness-related self-conscious emotions (SCEs) have been proposed as antecedents of exercise addiction (EA). However, the potential mechanisms underlying such a relationship remain unexplored. The present study examined the relationship between fitness-related SCEs and risk of EA, as well as the mediating role of passion for exercise. A total of 296 male runners (M = 40.35 years, SD = 10.69) completed a survey assessing weekly exercise frequency/hours, fitness-related SCEs, passion for exercise, and the risk of EA. The relationships between the study variables were examined using structural equation modeling. After controlling for age and weekly exercise frequency/hours, fitness-related SCEs of shame, guilt, and hubristic pride were positively associated with risk of EA. However, while guilt had direct effects on risk of EA, shame and hubristic pride showed indirect effects via obsessive passion. The results of the study are discussed, and some practical implications and future research directions are presented.

Physical appearance comparisons and symptoms of disordered eating: The mediating role of social physique anxiety in Spanish adolescents.

Physical appearance comparisons (PAC) and social physique anxiety (SPA) have been independently related to disordered eating (DE). However, the extent to which these variables may be concurrently associated with DE in the adolescent population remains largely unknown. This study was aimed at addressing a twofold objective: firstly, to examine whether SPA may moderate or mediate the relationship between PAC and DE in a sample of Spanish adolescents of both sexes; secondly, to examine whether these mechanisms may differ according to sex. A total of 738 adolescents (50% girls) ranging from 12 to 17 years of age (M = 14.45, SD = 1.50) were recruited from nine secondary schools. Participants completed a self-reported questionnaire covering the variables of interest. After controlling for the effects of sex, age, standardized body mass index (z-BMI), and depressive symptoms, the results from bootstrapping cross-sectional regression analyses supported the mediating effect of SPA on the relationship between PAC and DE, but not the moderating one. Sex was not found to moderate either the mediated or moderated relationships. Prevention/intervention efforts targeted towards decreasing DE among adolescents may benefit from minimizing the social relevance of the body inherent in the cognitive and affective processes underlying both SPA and PAC.

Examining the associations between the Big Five personality traits and body self-conscious emotions.

This study examined the relationships between the Big Five personality traits and body-related self-conscious emotions in a sex-balanced sample of Spanish undergraduates (N = 748). After controlling for sex, age, and weight discrepancy, neuroticism (positive for shame and guilt), extraversion (negative for shame and positive for pride), conscientiousness (negative for shame and positive for pride), and openness (negative for shame and guilt) emerged as significant cross-sectional predictors of body-related self-conscious emotions. No moderation effect by sex was observed. The explained variance ranged from 10% (hubristic pride) to 26% (shame). Young adults possessing greater than ideally assumed body weight, high levels of neuroticism, and low levels of extraversion, conscientiousness, and openness may be especially vulnerable to body-image disturbances.

Exploring the differentiated relationship between appearance and fitness-related social anxiety and the risk of eating disorders and depression in young adults.

Appearance-related social anxiety has been identified as a relevant risk factor in the development of eating disorders (ED) and depression in young adults. However, less is known about the role that fitness-related social anxiety may play on the emergence of these two psychopathological conditions. The present study aimed to examine whether appearance/fitness social anxiety may independently contribute to explaining the increased risk of ED and depressive symptoms in young adults. A total of 545 undergraduate students (46% women, Mage  = 21.36, SDage  = 2.93) recruited in two Spanish public universities completed a self-reported questionnaire. After controlling for self-reported BMI and appearance-related social anxiety, the results from the regression analyses revealed that fitness-related social anxiety positively and significantly (p < 0.05) contributed to explaining both the risk of ED (in women and men) and depressive symptoms (in women). The inclusion of the interaction term within the appearance/fitness-related term positively contributed to explaining additional variance for both the risk of ED and depressive symptoms in men, but not in women. The regression models explained 48% (women) and 35% (men) of the ED risk and 25% (women) and 19% (men) of depressive symptoms. These findings suggest that not only appearance, but also fitness-related social anxiety experiences may contribute to explaining the emergence of ED and depression in young adults.

Examining the relationship between fitness-related self-conscious emotions, disordered eating symptoms, and morbid exercise behavior: An exploratory study.

BACKGROUND AND AIMS: Theoretical models of morbid exercise behavior (MEB) suggest that it may emerge as a result of complex interactions between a range of psychosocial factors. However, in spite of fitness-related self-conscious emotions involving such factors, their relationship with the risk of MEB has never been investigated. Consequently, this study had two objectives. First, to explore the relationship that fitness-related self-conscious emotions have with (a) symptoms reflecting MEB as assessed by the Exercise Addiction Inventory (EAI) and the Exercise Dependence Scale-Revised (EDS-R) and (b) exercise frequency. Second, to examine whether these relationships might vary according to disordered eating symptoms. METHODS: A sample of 646 undergraduate students (59% males; Mage = 21.25; SDage = 2.94) completed a self-reported questionnaire. RESULTS: After controlling for age, sex, and disordered eating symptoms, it was found that shame, hubristic pride, and authentic pride positively explained MEB; for their part, guilt (negatively) and authentic pride (positively) explained exercise frequency. The positive relationships between pride and MEB were weaker (in the case of the hubristic facet) or stronger (in the case of the authentic facet) under higher levels of disordered eating symptoms. The independent variables explained 29% (EAI), 28% (EDS-R), and 27% (exercise frequency) of the variance in dependent variables. DISCUSSION: Tempering fitness-related emotions of shame, guilt, hubristic pride, and authentic pride may contribute to healthier exercise behavior.
