Reciprocal association between pain and quality of life after newly acquired spinal cord injury

PURPOSE

Pain is highly prevalent in spinal cord injury (SCI) and a key determinant of quality of life (QoL). This is the first study to examine reciprocal associations between pain and QoL in patients undergoing their first inpatient rehabilitation after SCI.

METHODS

Longitudinal data, with three measurement time points (1 month and 3 months after SCI onset, and at discharge from inpatient rehabilitation) from the Inception Cohort of the Swiss Spinal Cord Injury Cohort Study. Participants were 381 individuals aged ≥ 16 years with a newly diagnosed traumatic or non-traumatic SCI. 75.1% were male and the average age was 53.2 years. Random intercept cross-lagged panel models were conducted to examine the reciprocal association between pain intensity and QoL, as measured with the International SCI QoL Basic Data Set three individual items (satisfaction with life, physical health, and psychological health) and total score (mean of the three individual items).

RESULTS

Both item and total QoL scores increased over time. 1 month: 5.3 (SD = 2.7), 3 months: 5.9 (SD = 2.3), discharge: 6.6 (SD = 2.0). Participants reported relatively low levels of pain intensity that remained stable over the course of inpatient rehabilitation. 1 month: 2.7 (SD = 2.3), 3 months: 2.6 (SD = 2.4), discharge: 2.7 (SD = 2.5). There were no significant cross-lagged associations between QoL and pain intensity across time.

CONCLUSION

Results indicate that pain intensity does not predict changes in QoL during first rehabilitation, and vice versa. Associations between pain intensity and QoL reported by previous studies may be attributable to individual characteristics and timely events that simultaneously influence pain and QoL.

Reciprocal relationship between physical and social frailty among community-dwelling older adults

OBJECTIVE

Both physical and social frailty are risk factors for major adverse health-related outcomes and influence each other. However, the longitudinal causal relationship between physical and social frailty has not been clarified. This study aimed to determine the reciprocal relationship between physical and social frailty by age group.

METHODS

This study analyzed longitudinal data from a cohort study of older adults aged 65 years or older living in Obu City, Aichi Prefecture, Japan. The study included 2568 participants who participated in both a baseline assessment in 2011 and a follow-up assessment four years later. Participants participated in assessments of physical and cognitive function. Physical frailty was assessed using the Japanese version of the Cardiovascular Health Study criteria. Social frailty was assessed with five questions about daily social activities, social roles, and social relationships. A total frailty score was calculated for each frailty type and used in the cross-lagged panel analysis. The reciprocal relationship between physical and social frailty status was analyzed using a cross-lagged panel model in each of the young-old (n = 2006) and old-old (n = 562) groups.

RESULTS

In the old-old group, baseline physical frailty status predicted social frailty status four years later, and social frailty status at baseline predicted physical frailty status four years later. In the young-old group, the effect of social frailty status at baseline on physical frailty at four years was significant; however, the cross-lag effect from baseline physical frailty status to social frailty status at four years was insignificant, indicating that social frailty preceded physical frailty.

CONCLUSION

The reciprocal relationship between physical and social frailty differed by age group. The results of this study suggest the importance of considering age when planning strategies to prevent frailty. Although a causal relationship between both physical and social frailty was observed in old-old, social frailty preceded physical frailty in the young-old, suggesting that early prevention of social frailty is important for the prevention of physical frailty.

The temporal relationship between depressive symptoms and self-rated health across adulthood

Objective: Depressive symptoms have been found to relate to diminished self-rated health (SRH), which is a reliable index of general health. Despite such associations, there is limited research examining the bidirectional temporal relationship between these variables. The current study is the first to investigate the longitudinal relationship between depressive symptoms and SRH utilizing a cross-lagged panel analysis in a sample that spans adulthood (ages 18-93).Method: Data from the Virginia Cognitive Aging Project were used to examine the temporal relationship between depressive symptoms and SRH in a cross-lagged panel analysis using structural equation modeling.Results: A bidirectional temporal relationship, which was not moderated by age, was established between depressive symptoms and SRH.Conclusion: This article is the first to demonstrate that depressive symptoms and SRH influence each other reciprocally over time across adulthood, even after controlling for relevant variables. Considering the ubiquity and ramifications of depressive symptoms among American adults, these results highlight the importance of investigating mechanisms that could elucidate the link between the variables in question.

Effect of Club cell secretory proteins on the association of tobacco smoke and PAH co-exposure with lung function decline: A longitudinal observation of Chinese coke oven workers

BACKGROUND

Exposure to polycyclic aromatic hydrocarbons (PAH) and tobacco smoke is associated with epithelial damage and reduced lung function. Club cell secretory protein (CC16) is a known biomarker for lung epithelial cells. However, the potential relationships between PAH and tobacco smoke exposure, CC16 levels, and reduced lung function remain unclear.

OBJECTIVES

This longitudinal study aimed to explore the potential role of CC16 in the association of tobacco smoke and PAH co-exposure with lung function.

METHODS

We enrolled 313 workers from a coking plant in China in 2014 and followed them up in 2019. The concentrations of PAH and nicotine metabolites in urine were determined using high-performance liquid chromatography (HPLC) with a fluorescence detector and HPLC-tandem mass spectrometry, respectively. The plasma CC16 concentration was determined using an enzyme-linked immunosorbent assay.

RESULTS

An analysis of the generalized estimating equation showed that each 1-unit increase in log-transformation of the last tertile of trans-3'-hydroxycotinine (3HC) was associated with a 3.30 ng/ml decrease in CC16. Restricted cubic spline analysis revealed a significant nonlinear dose-effect association between cotinine (COT) and CC16 (P_nonlinear = 0.018). In the low- CC16 subgroup, we found a significant association between total nicotine metabolites and forced vital capacity (FVC%) (β: 1.45, 95% CI: 2.87, -0.03), and the associations of nicotine (NIC), COT, and 3HC with FVC% were all of marginal significance. High levels of total hydroxyl polycyclic aromatic hydrocarbons (ΣOH-PAH) and NIC in the urine had an interactive effect on the decline of CC16 (P < 0.05). Cross-lagged panel analysis indicated that the decrease in CC16 preceded the decrease in FVC%. CC16 mediated the association between elevated nicotine metabolites and decreased FVC% in the low- CC16 subgroup.

CONCLUSIONS

CC16 plays an essential role in the association of PAH and tobacco smoke exposure with reduced lung function. Coke oven workers with low plasma CC16 levels are more likely to experience decreased lung function after tobacco smoke exposure.

Longitudinal relationship between quality of life and negative life events among adolescents during COVID-19 pandemic: a cross-lagged panel analysis

BACKGROUND

The negative association of quality of life (QoL) and negative life evens (NLEs) among adolescents has been proved by cross-sectional studies, without exploring sex differences. This study aimed to explore the longitudinal associations between QoL and NLEs among adolescents during novel coronavirus disease 2019 (COVID-19) pandemic and whether there are sex or age differences.

METHODS

A stratified cluster sampling was used to select 1421 students in primary school and middle school in Chongqing, China. From November 2020 (T0) to December 2021 (T2), the Adolescent Self-Rating Life Events Checklist and the Adolescent Quality of Life Scale were used to collect 3 waves of data. The correlations between study variables were conducted by the Pearson correlation analyses. The direction and strength of the longitudinal associations were analyzed using cross-lagged panel analyses.

RESULTS

Results showed significant changes in both variables during COVID-19 pandemic (P < 0.001). Cross-sectional analyses showed stable negative correlations between NLEs and QoL stratified by sex or by age (P < 0.001). Sex and age differences in longitudinal relationships were shown by cross-lagged panel analyses. For males, NLEs had a short-term bi-directional association with QoL [βA-D = -(0.091-0.340), P < 0.05]; for females, QoL had a short-term correlation with NLEs [βA = -0.119), βC = -0.109), P < 0.001]. In the youngest age group, NLEs had a short-term bi-directional correlation with QoL [βA-D = -(0.098-0.428), P < 0.05]. There was a short-term association between total QoL and NLEs among students except the 14∼15 year group [βA = -(0.071-0.149), βC = -(0.086-0.119), P < 0.05], the long-term association between total QoL and NLEs was only significant in adolescents aged 14∼15 years (βE = -0.132, P < 0.05). The strength of NLEs was slightly higher than that of total QoL, but lower than that of QoL in each dimension.

CONCLUSION

There were negative longitudinal relationships between NLEs and QoL during COVID-19 pandemic, and the strength of the associations varied across sex or age. Strengthening QoL in different dimensions may be a promising way to reduce NLEs during the pandemic among adolescents, and interventions should be tailored according different sex and ages.

Interaction between self-perceived disease control and self-management behaviours among Chinese middle-aged and older hypertensive patients: the role of subjective life expectancy

Background

One of the effective ways to control hypertension is long-term self-management, which is difficult to maintain. Therefore, understanding how people engage in the process of self-management behaviour change is necessary. In this study, we aimed to examine the dynamic relationship between self-perceived disease control and self-management behaviours in Chinese middle-aged and older hypertensive patients, namely, medication use, self-monitoring, physical activity, tobacco and alcohol avoidance, and to explore the mediating role of subjective life expectancy (SLE) on this relationship.

Methods

Data were obtained from a nationally representative sample of 508 middle-aged and older hypertensive patients (aged 45+) from the 2013, 2015, and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey. A cross-lagged panel model combined with mediation analysis was used to determine the dynamic relationship between self-perceived disease control and self-management behaviours and to clarify the mediating effect of SLE on this ascertained relationship.

Results

Good self-perceived disease control subsequently predicted good medication use, self-monitoring and physical activity, and vice versa. Subjective life expectancy (SLE) partially mediated the prospective reciprocal relationships between self-perceived disease control and these self-management behaviours, which accounted for 37.11, 25.88, and 19.39% of the total effect of self-perceived disease control on medication use, self-monitoring and physical activity, respectively. These self-management behaviours had a significant and positive feedback effect on self-perceived disease control. However, neither the direct and indirect effects (via SLE) of self-perceived disease control on tobacco and alcohol avoidance were revealed.

Conclusions

Positive feedback loops of present self-perceived disease control, future SLE and self-management behaviours (medication use, self-monitoring, and physical activity) help middle-aged and older hypertensive patients adhere to these behaviours but are useless for the avoidance of addictive behaviours. Interventions aimed at enhancing the effect perception of general self-management behaviours (e.g., medication use, self-monitoring and physical activity) on the present disease control perspective, and future lifespan perspective would be beneficial for the consistent self-management behaviours of middle-aged and older hypertensive patients. The utility of present disease control perception to these self-management behaviours was much higher than the utility of future expectations. Alternative stress relief strategies may be conducive to long-term changes in addictive behaviours.

Interaction of polycyclic aromatic hydrocarbon exposure and high-fasting plasma glucose on lung function decline in coke oven workers: a cross-lagged panel analysis

Individuals with abnormal fasting plasma glucose (FPG) may be more susceptible to lung diseases associated with environmental pollutants. A cross-sectional survey of 629 workers in 2017 and a panel study of 304 workers from 2014 to 2019 were performed in China. The results showed that elevated total hydroxylated polycyclic aromatic hydrocarbon (ΣOH-PAH) concentration was associated with lower the percentage of predicted forced vital capacity (FVC%) among high-FPG workers (β for the cross-sectional analysis: -1.78%, 95%CI: -2.92%, -0.64%; β for the panel study: -1.10%, 95%CI: -2.19%, -0.02%). The absolute value of the cross-lagged path coefficient from FPG to FVC% (β₂ = -0.096) was significantly greater than that from FVC% to FPG (β₁ = 0.037). Our results suggest that FPG abnormalities may precede the lung function decline induced by PAH exposure and that high-FPG and high ΣOH-PAH levels have an interactive effect on lung function decline.

Psychotropic medication use and academic performance in adolescence: A cross-lagged path analysis

INTRODUCTION

The study investigated the directionality of associations between mental health problems and school grades across two timepoints (T1 and T2) during mid to late adolescence; in school year 9 (ages 15-16) and school year 12 (ages 17-18). The study also investigated variation in the associations as a function of gender and across socioeconomic groups.

METHODS

Longitudinal data from several Swedish administrative registers were utilised. Information on prescribed psychotropic drugs was used as a proxy for mental health problems, and teacher-assigned school grades were used to measure academic performance. The study sample comprised 85 186 individuals (50.7% girls) born in 1991 who were alive and resident in Sweden in 2010. Directions of associations were analysed by estimating a series of cross-lagged path models.

RESULTS

The model with the best fit to data showed that higher school grades at T1 were associated with relatively lower rates of mental health problems by T2, for both boys and girls, mainly in socioeconomic groups with the highest educated parents. This association was equal in size across all of the socioeconomic groups that were explored.

CONCLUSIONS

Performing well in school is equally important for boys' and girls' subsequent mental health, but only among adolescents in socioeconomic groups with the highest educated parents. The results underscore the importance of promoting opportunities for youth to do as well as they can in school.

The Bidirectional Relationship Between Subjective Well-Being and Academic Achievement in Adolescence

The well-being of young people in relation to their school performance has received increased attention in recent years. However, there is a lack of knowledge about the longitudinal and reciprocal relationship between adolescents' subjective well-being and their academic achievements. The current study examined the bidirectional relationship between subjective well-being and academic achievement across two timepoints (T1 and T2) during the course of mid to late adolescence, i.e., in school year 9 (age 15), and school years 11-12 (ages 17-18). The study also investigated variation in the association as a function of adolescent gender. Data on subjective well-being and teacher-assigned school grades of 723 adolescents (48.7% girls) residing in Sweden were analyzed by estimating a series of cross-lagged path models. The findings suggest gender differences in the relationship as no associations were found among boys. Support for a bidirectional relationship between the constructs was only found for girls. For girls, higher subjective well-being at T1 was associated with higher academic achievements at T2, while higher academic achievements at T1 was associated with lower subjective well-being at T2. These findings highlight that the subjective well-being of adolescent girls may be important for their ability to perform at school, but their academic achievements may also inflict negatively on their subjective well-being.

Maternal feeding style and child weight status among Hispanic families with low-income levels: a longitudinal study of the direction of effects

BACKGROUND

The home environment is a central and modifiable influence on the development of childhood obesity. Evidence supports the central role of parents in shaping problematic child eating behaviors and excess weight. Most studies of feeding emphasize parent-driven influences without taking into account the child's role in eating interactions. Few studies have addressed the bi-directional nature of feeding dynamics in studies of young children.

METHODS

The goals of this study were: 1) to examine if parental feeding styles during preschool (4-5 years) predict child weight status at 7-9 years, and 2) to examine the direction of effects between parental feeding styles and child weight status over time. Participants were part of a larger longitudinal study of Hispanic Head Start families living in the West South Central United States. Data from mother/child dyads were collected at three time points: Time 1 (ages 4-5), Time 2 (ages 5 ½-6 ½), and at Time 3 (ages 7-9). Only data from the Times 1 and 3 were used in the current analyses. A total of 128 mothers and their children had data on all variables needed for the analyses. Assessments included parent-reported feeding styles, feeding practices, acculturation, child eating behaviors, and child height and weight. Hierarchical regression was used to examine the first aim; a cross-lagged panel analysis examined the second aim.

RESULTS

An indulgent parental feeding style at ages 4-5 was associated with increased child BMI z-score at ages 7-9. Indulgent feeding significantly contributed to child BMI z-score beyond demographics, baseline child BMI z-score, parental acculturation, and child eating behaviors. Regarding the direction of effects in parental feeding interactions, the cross-lagged analyses showed that both indulgent feeding style and authoritative feeding style at Time 1 positively predicted child BMI z-scores at Time 3. Child effects were significant as well. Child BMI z-score at Time 1 positively predicted indulgent feeding and negatively predicted authoritarian feeding at Time 3.

CONCLUSIONS

Indulgent feeding should be addressed in future family-focused childhood obesity initiatives focused on young children and their parents.

A future time perspective of secondary school students' academic engagement and disengagement: A longitudinal investigation

Students' conceptions of their academic futures, such as completing secondary school, have been found to play a significant role in their current behavior. Indeed, research regarding future time perspectives (FTP) indicates that students with extended FTPs are likely to be more engaged and less disengaged over time. Extended FTPs comprise two critical motivating elements: the cognitive (i.e., importance value) and the dynamic (i.e., school completion aspirations). Although these elements are hypothetically reciprocally related and without temporal limitation to their motivational effects, these claims have largely gone untested. These claims were examined via longitudinal structural equation modelling with cross-lagged panel analysis and invariance testing in a sample of 1327 Australian secondary school students. Findings indicated that importance value is directionally salient over school completion aspirations (such that it may precede school completion aspirations), both are associated with higher engagement and lower disengagement over time, and evidence of temporal limitations on the motivational benefits of the elements of extended FTPs was not found. School-based interventions that focus on improving importance value and school completion aspirations are discussed.

Trauma-related cognitions predict treatment response in smokers with PTSD: Evidence from cross-lagged panel analyses

OBJECTIVE

Compared to smokers without posttraumatic stress disorders (PTSD), smokers with PTSD smoke more heavily and are less successful in quitting smoking. However, limited research has examined the cognitive pathways underlying this heightened comorbidity. The current study is the first to simultaneously model the cross-sectional and lagged relationships between trauma-related cognitions and cigarette smoking, as well as between trauma-related cognitions and PTSD severity, in smokers with comorbid PTSD receiving treatment.

METHOD

Participants (n = 142) were seeking treatment for smoking cessation and PTSD as part of a randomized controlled trial of varenicline and smoking cessation counseling with or without adjunctive Prolonged Exposure (varenicline + PE vs. varenicline only) (Foa et al., 2017). Data were available for both baseline and end-of-treatment assessments of trauma cognitions severity of cigarette smoking and PTSD symptoms. We conducted both cross-sectional and lagged analysis to simultaneously examine the bidirectional relationship from trauma cognitions and 1) cigarette smoking and 2) PTSD symptoms.

RESULTS

Trauma cognitions (specifically, negative beliefs about the self and the world) were significantly associated with cigarette/day at the end of treatment for participants who received varenicline only. However, baseline trauma cognitions did not predict post-treatment cigarettes/day. Baseline trauma cognitions (specifically negative beliefs about the self and world) were associated with PTSD severity at both baseline and end of treatment; furthermore, these negative cognitions at baseline positively and prospectively predicted end-of-treatment PTSD severity, but not vice versa. Wald tests revealed that there were no treatment effects on these cross-lagged relationships. Conclusions These findings provide novel empirical support for the importance of addressing trauma-related cognitions in the smoking cessation treatment efforts for patients with comorbid PTSD and cigarette smoking.

Hyperuricemia precedes non-alcoholic fatty liver disease with abdominal obesity moderating this unidirectional relationship: Three longitudinal analyses

BACKGROUND AND AIMS

The temporal relationship between hyperuricemia and non-alcoholic fatty liver disease (NAFLD) is debatable. This study aimed to explore whether there exists a bidirectional or temporal relationship between them.

METHODS

A total of 11,585 participants were recruited from the Beijing Health Management Cohort during the period 2012-2016. We evaluated whether hyperuricemia was associated with NAFLD development (part I) and whether NAFLD was associated with hyperuricemia incidence (part II) using a logistic regression model. Further, the cross-lagged panel analysis model was used to simultaneously examine the bidirectional relationship between hepatic steatosis and serum uric acid (SUA) (part III). Subgroup and interaction analyses were also performed to assess whether other variables moderated those relationships.

RESULTS

In part I, multiple logistic regression indicated that baseline hyperuricemia was associated with the development of NAFLD (OR = 1.5970, p < 0.0001). In part II, multiple logistic regression showed that baseline NAFLD was not correlated with hyperuricemia incidence (OR = 0.8600, p = 0.1976). In part III, cross-lagged panel analyses indicated that the standard regression coefficient of baseline SUA to follow-up hepatic steatosis (0.1516) was significantly greater than the coefficient from the baseline hepatic steatosis to follow-up SUA (-0.0044) with p < 0.0001 for the difference. This indicated a unidirectional relationship from baseline SUA to follow-up hepatic steatosis, suggesting hyperuricemia may precede NAFLD; and this relationship was not affected by age, sex, dyslipidemia, metabolism syndrome, diabetes but was moderated by abdominal obesity.

CONCLUSIONS

This study demonstrated a unidirectional relationship from hyperuricemia to NAFLD incidence, and suggested that lowering SUA levels in hyperuricemia patients may prevent subsequent NAFLD.

School alienation and academic achievement in Switzerland and Luxembourg: a longitudinal perspective

Early adolescence represents a particularly sensitive period in the life of young learners, which is accompanied by an increase in school alienation. Due to its harmful nature (Hascher and Hadjar in Educ Res 60:171-188, 2018. 10.1080/00131881.2018.1443021), school alienation may lead to unfavorable consequences such as low academic achievement (Johnson in J Educ Technol Soc 8:179-189, 2005; Reinke and Herman in Psychol Schools 39:549-559, 2002). This study investigates the longitudinal relationship between school alienation domains, namely alienation from learning, from teachers, and from classmates, and academic achievement among secondary school students of grade 7 to grade 9 in Switzerland and Luxembourg. Data were collected from 403 students in the Swiss canton of Bern and 387 students in Luxembourg who participated in three waves of the "School Alienation in Switzerland and Luxembourg (SASAL)" research project. Cross-lagged modeling was applied to examine the correlations between school alienation domains and academic achievement at each of the three time points, the temporal stability of school alienation domains and academic achievement, and their cross-lagged effects across time, controlling for students' gender, school track, parental occupational status, and migration background. Results show that the pattern of relationships is defined by the school alienation domain and the cultural context, pointing to the complex interplay between the multidimensional construct of school alienation and academic outcomes of secondary school students.

Weight/shape and muscularity concerns and emotional problems in adolescent boys and girls: A cross-lagged panel analysis

INTRODUCTION

The goal of the present study was to identify the prospective relations between weight/shape and muscularity concerns and emotional problems in adolescents.

METHODS

Self-report data of 966 German male and female adolescents were analyzed in a cross-lagged panel design.

RESULTS

Analyses of latent means revealed significant correlations between weight/shape concern and emotional problems as well as between muscularity concern and emotional problems in both genders. Moreover, weight/shape concern predicted emotional problems prospectively, but only in girls. Regarding muscularity concern, we could not find any prospective relation with emotional problems in boys or girls from the general population.

CONCLUSIONS

It is assumed that as appearance is highly relevant for the self-concept in girls, concerns about the look might promote emotional problems. Thus, weight/shape concern should be addressed in the prevention of emotional problems in adolescent girls, whereas further research is necessary investigating the contribution of muscularity concern in this context.

Loneliness and Cognitive Function in Older Adults: Findings From the Chinese Longitudinal Healthy Longevity Survey

OBJECTIVES

To examine the relationship between loneliness and cognitive function and to explore the mediating role of physical health on the loneliness-cognition relationship in Chinese older adults (OAs).

METHOD

Data came from a nationally representative sample of 14,199 Chinese OAs (aged 65+) from 2002, 2005, 2008, and 2011 waves of the Chinese Longitudinal Healthy Longevity Survey. A latent variable cross-lagged panel model combined with mediation analysis was used to determine the relationship between loneliness and cognitive function and the mediating effect of increase in the number of chronic conditions (ΔNCCs) on the ascertained loneliness-cognition relationship.

RESULTS

Severe loneliness at prior assessment points was significantly associated with poorer cognitive function at subsequent assessments, and vice versa. The ΔNCCs partially mediated this prospective reciprocal relationships, accounting for 2.58% of the total effect of loneliness on cognition and 4.44% of the total effect of cognition on loneliness, respectively.

DISCUSSION

Loneliness may predict subsequent cognitive decline, and vice versa. This loneliness-cognition relationship is partially explained by their impact on physical health. Multidisciplinary interventions aimed at reducing loneliness and cognitive decline per se and their associated risk factors as well as improving chronic illness management would be beneficial for emotional well-being and cognitive health in OAs.

The relationship of self-compassion and depression: Cross-lagged panel analyses in depressed patients after outpatient therapy

BACKGROUND

Previous cross-sectional studies suggest that self-compassion and depressive symptoms are consistently negatively associated. Although it is often implicitly assumed that (a lack of) self-compassion precedes depressive symptoms, so far no study has tested whether (lack of) self-compassion is a cause or a consequence of depressive symptoms, or both.

METHOD

To examine such reciprocal effects, we used data of 125 depressed outpatients after a time limited cognitive-behavioral psychotherapy. We assessed self-compassion and depressive symptoms via self-report measures and the presence of a major depressive episode directly after therapy, as well as 6 and 12 months later.

RESULTS

Cross-lagged panel analyses indicated that (lack of) self-compassion significantly predicted subsequent depressive symptoms while controlling for autoregressive effects, whereas depressive symptoms did not predict subsequent levels of self-compassion. This was also the case for the relationship between self-compassion and the presence of a major depressive episode. The same patterns also occurred when we separately tested the reciprocal effects for two composite sub-measures of either positive or negative facets of self-compassion.

LIMITATIONS

Causality cannot be inferred from our results. Depressive symptoms and self-compassion could still be causally unrelated, and a third variable could account for their negative association.

CONCLUSIONS

These findings support the notions that (a lack of) self-compassion could serve as a vulnerability factor for depression and that cultivating self-compassion may deserve a focus in depression prevention programs or treatments.
