The Association between Discrepancies in Parental Emotional Expressivity, Adolescent Loneliness and Depression: A Multi-Informant Study Using Response Surface Analysis.

Incongruent perceptions of parental emotional expressivity between parents and adolescents may signify relational challenges, potentially impacting adolescents' socioemotional adjustment. Direct evidence is still lacking and father-adolescent discrepancies are overlooked. This study employed a multi-informant design to investigate whether both mother-adolescent and father-adolescent discrepancies in perceptions of parental expressivity are related to adolescents' mental well-being, specifically focusing on loneliness and depression. Analyzing data from 681 families (mean age of adolescents = 15.5 years old, 51.2% girls, 40% only-children) in China revealed that adolescents tended to perceive paternal and maternal emotional expressivity more negatively than their parents, particularly fathers. Polynomial regression and response surface analysis showed significant links between parent-adolescent congruence and incongruence and adolescent loneliness. (In)Congruence between adolescents and mothers or fathers predicted later adolescent depression, mediated by adolescent loneliness and varied by the dimension of emotional expressivity. These findings provide insights into the roles of mothers' and fathers' emotional expressivity in shaping children's mental well-being during adolescence.

Discrepancies in Parent-Child Perception of Parental Control and Associations with Children's Anxiety: The Buffering Effect of Parent-Child Closeness.

Previous research has predominantly relied on single-informant reports to establish the association between parental control and children's anxiety. However, there remains ambiguity regarding the extent to which discrepancies in parent-child reports of parental control are related to children anxiety. This study examined parent-child perceived discrepancies in parental control and their association with children's anxiety, along with the moderated effect of parent-child closeness through cross-sectional and prospective analysis. The sample consisted of 790 children (Mage = 11.34, SD = 6.73, 45.60% for girls), with 741 father-child dyads and 760 mother-child dyads included. Data were analyzed using polynomial regressions with response surface analysis. The results indicated that children tended to perceive higher levels of parental psychological control and lower levels of behavioral control compared to their parents' perceptions. In the cross-sectional analysis, a significant association between greater incongruence in psychological/behavioral control and higher levels of children's anxiety at T1 was observed exclusively in father-child dyads. In prospective analysis, for both father-child and mother-child dyads, congruence in higher levels of psychological control was associated with higher levels of children's anxiety at T2, while congruence in higher levels of behavioral control was associated with lower levels of children's anxiety at T2. Additionally, greater incongruence in psychological/behavioral control was linked to higher levels of children's anxiety at T2. Furthermore, mother-child closeness emerged as a significant moderator such that perceived incongruence in psychological/behavioral control could not affect children's anxiety at T2 in the high mother-child closeness condition. These findings highlight the significance of considering parent-child congruence and incongruence when examining the impact of parental control on children's anxiety.

Inconsistency in psychological resilience and social support with mental health in early adolescents: A multilevel response surface analysis approach.

BACKGROUND: Given the high prevalence of adolescent mental health problems, promoting understanding and implementation of protective factors is crucial for prevention and intervention efforts addressing adolescent mental health problems. This study aims to investigate whether consistency and inconsistency in protective factors are associated with adolescent mental health problems and to inform adolescent mental health interventions that target the unique needs of adolescents and promote adolescent mental health. METHODS: We used multistage cluster sampling to conduct psychological resilience, social support, and mental health questionnaires from April to June 2023 among 10,653 Chinese adolescents (52.3 % were boys). Data were analyzed using polynomial regressions with response surface analysis. RESULTS: The higher levels of psychological resilience and social support in adolescents were associated with fewer mental health problems (anxiety: a1 = -1.83, P < 0.001; depression: a1 = -2.44, P < 0.001; and perceived stress: a1 = -1.20, P < 0.001). When the level of psychological resilience was greater than social support, the greater the discrepancy the higher the perceived stress among adolescents (a3 = 1.19, P < 0.001). Moreover, the consistency of psychological resilience and social support had a greater impact on girls' mental health (anxiety: a1 = -1.97, P < 0.001; depression: a1 = -2.71, P < 0.001; perceived stress: a1 = -1.23, P < 0.001). LIMITATIONS: The cross-sectional study design limited the inference of causal relationships between variables. CONCLUSIONS: These results emphasize that adolescents need a balanced development of protective factors and targeted intervention programs for different mental health problems.

Discrepancies in perceived family resilience between adolescents with chronic illness and parents: using response surface analysis to examine the relationship with adolescents' psychological adjustment.

BACKGROUND: This study aimed to explore discrepancies in adolescents with chronic illness and their parents' perceptions of family resilience, as well as the relationship between these differences and the psychological adjustment of adolescents with chronic illness. METHODS: A cross-sectional study was conducted. A total of 264 dyads of parents (77.7% mothers, mean age 41.60 years, SD = 6.17) and adolescents (48.5% girls, mean age 12.68 years, SD = 2.11) with chronic illness were recruited through convenience sampling from three children's hospitals in Wenzhou, Hangzhou, and Shanghai, China between June 2022 and May 2023. The Chinese version of the Family Resilience Scale and the Psychological Adjustment Scale, which are commonly used measures with good reliability and validity, were employed to assess family resilience and psychological adaption, respectively. The data were analyzed using polynomial regression and response surface analysis. RESULTS: Adolescents with chronic illness reported higher family resilience than their parents (t=-2.80, p < 0.05). The correlations between family resilience and adolescents' psychological adjustment reported by the adolescents (r = 0.45-0.48) were higher than parents (r = 0.18-0.23). In the line of congruence, there were positive linear (a1 = 1.09-1.60, p < 0.001) and curvilinear (a2=-1.38∼-0.72, p < 0.05) associations between convergent family resilience and adolescents' psychological adjustment. In the line of incongruence, when adolescents reported lower family resilience than parents, adolescents had a lower level of psychological adjustment (a3=-1.02∼-0.45, p < 0.05). Adolescents' sociability decreased when the perceived family resilience of parent-adolescent dyads converged (a4 = 1.36, p < 0.01). CONCLUSION: The findings highlighted the importance of considering the discrepancies and congruence of family resilience in the parent-child dyads when developing interventions to improve the psychological adjustment of adolescents with chronic illness. Interventions aimed at strengthening family communication to foster the convergence of perceptions of family resilience in parent-adolescent dyads were warranted.

Combined effect of compassionate and uncompassionate self-responding on Chinese college students' mental health during the initial wave of the COVID-19 pandemic: a response surface analysis.

Background: The initial wave of the COVID-19 pandemic significantly deteriorated mental health, especially among college students. Self-compassion has demonstrated benefits for psychological outcomes such as depressive symptoms, life satisfaction, posttraumatic stress symptoms (PTSS), and posttraumatic growth (PTG). Notably, existing literature suggests that the protective and vulnerable aspects within the Self-Compassion Scale, namely, compassionate and uncompassionate self-responding (CSR and USR), can coexist within individuals and influence their mental health through various coexisting patterns. However, this process has not been sufficiently explored.Objective: This study aimed to explore the combined effects of CSR and USR on college students' depressive symptoms, life satisfaction, PTSS, and PTG during the initial wave of the pandemic.Method: In this cross-sectional study, 4450 Chinese college students (51.9% females, Mage = 20.58 years, SD = 1.49) completed self-report measures amid the COVID-19 pandemic's initial wave in 2020. Response surface analyses were utilised to investigate the combined effects of CSR and USR.Results: Simultaneously increased CSR and USR were associated with a slight increase in depressive symptoms, PTSS, and life satisfaction, but a substantial increase in PTG. Conversely, increased CSR and decreased USR were associated with a considerable decrease in depressive symptoms and PTSS, a significant increase in life satisfaction, and a moderate increase in PTG.Conclusions: CSR and USR demonstrated protective and vulnerable impacts, respectively. It is imperative to analyse their combined effects as an interactive system and consider the specific characteristics of different psychological responses.

Increased CSR and decreased USR were associated with less depressive symptoms and PTSS as well as more life satisfaction.CSR mitigated the negative effects of USR on depressive symptoms, life satisfaction, and PTSS.Simultaneously increased CSR and USR were associated with a substantial increase in PTG.

Social support and family resilience among Chinese people receiving maintenance hemodialysis: A polynomial regression and response surface analysis explaining psychological resilience.

Psychological resilience plays an important role in overcoming emotional distress among people receiving maintenance hemodialysis (MHD). This study aimed to investigate how social support and family resilience interact to influence psychological resilience among Chinese people receiving MHD. This was a prospective longitudinal study with three time points: baseline (T1), 3 months (T2), and 6 months (T3) later. A convenience sample of 252 participants (67.1% male; 57.6 ± 13.8 years of age) from Zhejiang Province, China, who completed baseline measures of social support, family resilience, and psychological resilience, were further assessed for psychological resilience at T2 and T3. Polynomial regression (PR) and response surface analysis (RSA) were used to analyze the data. At all time points, and in the case of agreement between social support and family resilience, the combined effect of both variables manifested as a positive linear association with psychological resilience. Instead, at baseline, and in case of disagreement, the same combined effect manifested as a negative linear relationship related to psychological resilience. The findings highlighted the importance of considering the conjoint influence of social support and family resilience when developing interventions to improve the psychological resilience of people receiving MHD.

Birth expectations, birth experiences and childbirth-related post-traumatic stress symptoms in mothers and birth companions: Dyadic investigation using response surface analysis.

OBJECTIVES: During the perinatal period, women and their birth companions form expectations about childbirth. We aimed to examine whether a mismatch between birth expectations and experiences predict childbirth-related post-traumatic stress symptoms (CB-PTSS) for mothers and birth companions. We also explored the influence of the mismatch between mothers' and birth companions' expectations/experiences on CB-PTSS. DESIGN: Dyadic longitudinal data from the Self-Hypnosis IntraPartum Trial. METHODS: Participants (n = 469 mothers; n = 358 birth companions) completed questionnaires at 27 and 36 weeks of gestation and 2 and 6 weeks post-partum. We used the measures of birth expectations (36 weeks gestation), birth experiences (2 weeks post-partum) and CB-PTSS (6 weeks post-partum). RESULTS: Correlations revealed that birth expectations were associated with experiences for both mothers and birth companions but were not consistently associated with CB-PTSS. Birth experiences related to CB-PTSS for both mothers and birth companions. The response surface analysis results showed no support for the effect of a mismatch between expectations and experiences on CB-PTSS in mothers or birth companions. Similarly, a mismatch between mothers' and birth companions' expectations or experiences was unrelated to CB-PTSS. CONCLUSIONS: Following previous literature, birth expectations were associated with experiences, and experiences were associated with CB-PTSS. By testing the effect of the match between birth experiences and expectations using an advanced statistical method, we found that experiences play a more substantial role than the match between experiences and expectations in CB-PTSS. The impact of birth experiences on CB-PTSS highlights the importance of respectful and supportive maternity care.

The effects of demand-resource relationship on work-family conflict under Chinese culture: a cross-sectional study.

Chinese work and lifestyle are undergoing dramatic changes caused by constantly changing technology and new policies. The demand-resource dynamic relationship, which leads to work-family conflict (WFC), has become increasingly complicated. However, very little is known about the combined effects of different factors from work and family spheres on WFC. This study aims to explore (1) the discrepancy between fit and misfit, (2) the discrepancy of the different degrees of fit, and (3) the discrepancy of the different degrees of misfit from two perspectives: work demand-family resource and work resource-family demand. Data were collected from 745 individuals in China and analyzed using polynomial regression and response surface. The results demonstrate that individuals having low work demand-high family resources experience the lowest WFC, and the fit between work demands and family resources impacts the conflict in a U way. Similarly, high work resource-low family demand results in the lowest WFC; however, the fit between work resources and family demands has negative effects on the conflict. This study took factors from both family and work domains into consideration and explored the effect of their interaction on WFC. By examining the dynamic relationship between demands and resources, adjustments can be made in both domains simultaneously, providing more flexible guidance for management practices that reduce WFC.

Optimization of High-Density Fermentation Conditions for Saccharomycopsis fibuligera Y1402 through Response Surface Analysis.

Saccharomycopsis fibuligera, which produces enzymes like amylase and protease as well as flavor substances like ß-phenyl ethanol and phenyl acetate, plays a crucial role in traditional fermented foods. However, this strain still lacks a high-density fermentation culture, which has had an impact on the strain's industrial application process. Therefore, this study investigated the optimization of medium ingredients and fermentation conditions for high-density fermentation of S. fibuligera Y1402 through single-factor design, Plackett-Burman design, steepest ascent test, and response surface analysis. The study found that glucose at 360.61 g/L, peptone at 50 g/L, yeast extract at 14.65 g/L, KH2PO4 at 5.49 g/L, MgSO4 at 0.40 g/L, and CuSO4 at 0.01 g/L were the best medium ingredients for S. fibuligera Y1402. Under these conditions, after three days of fermentation, the total colony count reached 1.79 × 108 CFU/mL. The optimal fermentation conditions were determined to be an initial pH of 6.0, an inoculum size of 1.10%, a liquid volume of 12.5 mL/250 mL, a rotation speed of 120 r/min, a fermentation temperature of 21 °C and a fermentation time of 53.50 h. When fermentation was conducted using the optimized medium and conditions, the total colony count achieved a remarkable value of 5.50 × 109 CFU/mL, exhibiting a substantial increase of nearly 31 times the original value in the optimal culture medium. This significant advancement offers valuable insights and a reference for the industrial-scale production of S. fibuligera.

Client preferences, therapy activities and preference-activity match as predictors of therapy outcome.

OBJECTIVE: This study investigated whether distinct types of psychotherapy activities, the client's preference towards these activities prior to therapy, and the degree of match between client preferences and therapy activities, served as predictors of treatment outcomes. METHODS: A total of 621 clients (Mage = 42 years, 71.7% female) received individual psychotherapy by 54 psychologists. Associations between activity preferences, therapy activities, and preference-activity match as predictors, and symptom change and treatment dropout as outcomes were analyzed using multilevel longitudinal and logistic modelling and polynomial regression models with response surface analysis. RESULTS: No type of therapy activity or activity preference significantly predicted symptom change in therapy, while higher levels of inward orientation therapy activities predicted an increased risk of dropout. Moreover, matching and higher levels of inward orientation and affect expression activities predicted an increased risk of dropout, and matching and higher levels of outward orientation activities predicted a decreased risk of dropout. Finally, a preference-activity mismatch in affect suppression predicted an increased risk of dropout from therapy, both at higher and lower levels of affect suppression. CONCLUSION: Distinct types of therapy activity preferences may, especially when (mis)matched with similar levels of the same therapy activities, differentially predict particular dropout from therapy.Trial registration: ClinicalTrials.gov identifier: NCT05630560.

Iron particle-integrated anammox granules in baffled reactor: Enhanced settling property and nitrogen removal performance.

This study evaluates iron particle-integrated anammox granules (IP-IAGs) to enhance wastewater treatment efficiency. The IP-IAGs resulted in notable improvements in settleability and nitrogen removal. The settling velocity of IP-IAGs increased by 17.91 % to 2.92 ± 0.20 cm/s, and the total nitrogen removal efficiency in batch mode improved by 6.82 %. These changes indicate enhanced biological activity for effective treatment. In continuous operation, the IP-IAGs reactor showed no accumulation of nitrite until 40 d, reaching a peak nitrogen removal rate (NRR) of 1.54 kg-N/m3·d and a nitrogen removal efficiency of 82.61 %. Furthermore, a partial nitritation-anammox reactor that treated anaerobic digestion effluent achieved a NRR of 1.41 ± 0.09 kg-N/m3·d, proving the applicability of IP-IAGs in real wastewater conditions. These results underscore the potential of IP-IAGs to enhance the efficiency and stability of anammox-based processes, marking a significant advancement in environmental engineering for wastewater treatment.

Interplay of Adolescents' and Parents' Mindsets of Socioeconomic Status on Adolescents' Stress-Related Outcomes.

The reciprocity and variation of values and beliefs are dynamic features of the parent-child relationship. Parents and adolescents may hold congruent or incongruent views regarding the malleability of socioeconomic status (mindset of SES), potentially influencing adolescents' psychological and physiological stress outcomes, as reflected in stress perceptions and the hypothalamic-pituitary-adrenal (HPA) axis functioning. The current study investigated how patterns of parent-adolescent congruence and incongruence in mindset of SES were associated with adolescents' perceived stress and diurnal cortisol patterns four months later. A total of 253 adolescents (Mage = 12.60, 46.2% girls) and their parents (Mage = 40.09 years, 59.5% mothers) participated in this study. Polynomial regression analyses and response surface analyses showed that adolescents perceived lower levels of stress when they themselves or their parents reported a stronger growth mindset of SES. Additionally, adolescents with a stronger growth mindset of SES also exhibited a steeper diurnal cortisol slope. Moreover, parents' mindset significantly interacted with adolescents' mindset to influence adolescents' diurnal cortisol patterns such that when adolescents hold weaker growth mindset of SES, those with higher parental growth mindsets had significantly higher cortisol awakening response and steeper diurnal cortisol slope. Furthermore, adolescents who showed incongruence with their parents but had averagely stronger growth mindsets of SES reported a significantly steeper diurnal cortisol slope than those who had averagely weaker growth mindsets with their parents. The findings point to the beneficial impacts of the growth mindset of SES on stress-related outcomes among adolescents, as well as the significance of considering both parents' and adolescents' mindsets when exploring these associations.

Parent-adolescent discrepancies in educational expectations, relationship quality, and study engagement: a multi-informant study using response surface analysis.

Whether parental educational expectations for adolescents serve as a source of motivation or stress depends on the extent to which adolescents hold expectations for themselves. Previous research on the discrepancies between parental and adolescent educational expectations and their impact on learning engagement has been limited by traditional statistical tests, and lacking an examination of the internal mediating mechanism of parent-child relational quality from both parental and adolescent perspectives. This cross-sectional study, utilizing a multi-informant design, examined the association between discrepancies in parents' and adolescents' reports of expectations, and adolescents' study engagement, as well as the mediating role of parent-child relational qualities perceived by both parties. The sample for this study consisted of 455 adolescents and their parents from 10 classes in a junior high school in Wuhan, Hubei Province, China. The adolescents had an average age of 12.8 years, and 51.6% of them were boys. Both parents and adolescents reported on their expectations and perceived relational quality, while adolescents also filled out questionnaires assessing their learning engagement. Data were analyzed using polynomial regressions with response surface analysis. The results revealed that when adolescents reported high expectations, regardless of whether their parents reported high or low expectations, adolescents reported satisfied relationships and high learning engagement. In contrast, parents reported satisfied relationships when both parties reported high expectations, or when parents reported higher expectations than adolescents. Lastly, the association between discrepancies in expectations and learning engagement was significantly mediated by adolescent-reported relationships but not parent-reported ones. These findings highlight the importance of considering multiple perspectives when studying the association between expectations and adolescent study engagement. This research advances our comprehension of the dynamics between parent-adolescent educational expectation discrepancies and adolescent learning engagement, offering insights for more nuanced and effective parenting strategies tailored to foster optimal educational outcomes.

Parent-child educational aspiration congruence and adolescents' internalizing problems: The moderating effect of SES.

Previous studies have found that adolescents and their parents may hold discrepant views about educational aspirations. However, little is known about how these discrepancies affect adolescents' internalizing problems and the moderating effect of SES on the relation between (in)congruence of parent-child educational aspirations and adolescents' internalizing problems. Therefore, this study explored the relation between (in)congruence of parent-child educational aspirations and adolescents' internalizing problems, and further tested the moderating role of SES. Based on two-wave survey data collected from a nationally representative sample of 8194 parent-child dyads in China (51.3 % boys, mean age = 13.58 years), multilevel polynomial regression and response surface analysis were performed to investigate the hypotheses. The results found that (1) internalizing problems were minimal when the two educational aspiration variables were congruent, (2) internalizing problems were the highest when the discrepancy between child educational and parental educational aspirations was largest, and (3) SES moderated the relation between (in)congruence in educational aspirations and adolescents' internalizing problems. The study's results not only comprehensively and intuitively reveal the influence of parents' and children's educational aspirations on adolescents' internalizing problems, but also provide targeted guidance and suggestions regarding parenting practices for families from diverse SES backgrounds.

Does Grit Compensate for Family Background Disadvantage in Predicting Mental Health Difficulties? A Longitudinal Study of Chinese Migrant and Urban Children.

The significant population of Chinese rural-to-urban migrant children has sparked considerable domestic and international concern regarding their disadvantaged family circumstances and their escalating prevalence of internalizing and externalizing problems. Derived from the resource substitution hypothesis, non-cognitive factors such as personality traits may act as "substitution" resources for educational outcomes of children from less privileged families. Yet, the compensatory role of personality traits as substitution resources in children's mental health has received limited attention, including that of migrant children. This study examined the interplay of trait-like grit and family SES on emotional and conduct problems among Chinese migrant and urban children. The current sample consisted of 770 migrant children (Mage = 10.45 and SDage = 0.68 years; 38.4% girls) and their 222 urban counterparts (Mage = 10.34 and SDage = 0.46 years; 45.5% girls). Moderated polynomial regressions with response surface analysis on a two-wave data with an interval of over six months showed that grit served as a "substitution" resource for the less socioeconomically advantaged children. The compensatory effect of perseverance of effort on urban children's emotional problems and that of consistency of interest on migrant children's conduct problems were visualized. Moreover, the two compensatory effects were found to be robust and unique, even after children's effortful control, a grit-related construct, was taken into account. These findings not only support the resource substitution hypothesis, but also underscore the protective role that grit plays in children under less privileged environments.

Is it okay to feel this way? Exploring the joint effect of emotional experiences and expectations on life satisfaction.

This research investigates the joint effect of individual emotional experiences and societal expectations on life satisfaction. Inspired by the Affect Valuation Theory and Self-Discrepancy Theory, we explored how discrepancies between actual emotional experiences and what society believes we "ought" to feel are linked with life satisfaction. A total of 301 U.S. online participants rated their emotional experiences and societal expectations for emotions, along with measures of life satisfaction. Response surface analyses were used to assess the effect of emotional experience-norm congruence on life satisfaction. Findings revealed that the highest life satisfaction reported by individuals infrequently experiencing negative emotions but perceiving high societal expectations for these emotions, while congruence effects were not supported. These findings suggest the potential benefits of a societal shift toward greater acceptance of a wider range of negative emotions. The study may potentially stimulate interventions to enhance individuals' life satisfaction by reconsidering societal beliefs about emotions.

Flash extraction of ulvan polysaccharides from marine green macroalga Ulva linza and evaluation of its antioxidant and gut microbiota modulation activities.

In this study, flash extraction was used to rapidly extract water-soluble polysaccharides from Ulva linza. The optimal extraction process for the flash extraction was determined by Box-Behnken design with extraction temperature 80 °C, extraction time 117 s, liquid-solid ratio 46:1 (mL/g) and a corresponding yield of 18.5 %. The crude Ulva linza polysaccharides (CULP) were subsequently isolated by chromatography technology to obtain purified Ulva linza polysaccharide (ULP) and characterized by monosaccharide composition and molecular weight determination analysis. Furthermore, the antioxidant bioactivity of ULP was studied and the results revealed that it had a good scavenging effect on DPPH, ABTS and OH, with IC50 values of 149.2 µg/mL, 252.5 µg/mL and 1073 µg/mL, respectively. After in vitro fermentation by human fecal microbiota, the pH value of fermentation culture significantly decreased to 5.06, suggesting that ULP could be hydrolyzed and utilized by gut microbiota. The abundance of beneficial bacteria including Bacteroides, Parabacteroides and Faecalibacterium was improved. Meanwhile, the relative abundance of Prevotella, Blautia and Ruminococcus was decreased, and the low ratio of these organisms might reveal positive effects on maintaining the balance of gut microbial biodiversity. These results suggested that the composition of the human gut microbiota could be modulated by ULP, and ULP might possess the potential to maintain gut homeostasis and improve human intestinal health.

The effect of mindfulness and psychological capital on mental health of breast cancer patients: Based on polynomial regression and response surface analysis.

OBJECTIVE: To explore the combined effects of mindfulness and psychological capital on mental health of breast cancer patients and to examine the mediating effect of positive emotions in their relationship. METHODS: A convenient sampling method was used in this study, and 522 breast cancer patients aged 18 to 59 who received chemotherapy in a tertiary cancer hospital were enrolled. Polynomial regression with response surface analysis was mainly employed to explore the relationship between mindfulness, psychological capital, and mental health. A block-variable approach was used to verify the mediating effect of positive emotions. RESULTS: In cases of congruence, mental health was better when mindfulness and psychological capital were both high instead of being both low (the slope of the congruence was 0.540, p < 0.001); In cases of incongruence, poorer mental health was found in breast cancer patients with low psychological capital and high mindfulness compared with those who had high psychological capital and low mindfulness (the slope of the incongruence was -0.338, p < 0.001), and the combined effects were a positive curve (positive U-shaped) related to mental health (ß = 0.102, p = 0.040). In addition, positive emotions played a mediating role in the relationship between the block variable (mindfulness and psychological capital) and mental health, and the indirect effect was 0.131. CONCLUSIONS: This study expanded the research on the effects of mindfulness and psychological capital in improving mental health as well as the conflict between the two variables related to mental health by employing a new analytical technique among breast cancer patients.

Examining therapist estimation of client working alliance and client symptom outcome using truth and bias model and response surface analysis.

OBJECTIVE: The aims of this study were to investigate the congruence and discrepancy between Chinese therapist trainees' estimated client working alliance (WA) and their clients' actual WA rating, and how the congruence and discrepancy predicted client symptom outcome. METHODS: Participants were 211 beginning therapist trainees and 1216 clients. Data from their 6888 sessions were analyzed using Truth and Bias Model and Response Surface Model. RESULTS AND CONCLUSIONS: (i) Chinese trainees' estimation of client WA was on average significantly lower than actual client WA. (ii) At the between-person level, whether the trainee generally over- or underestimated client WA was not related to the client's initial symptom level or symptom improvement rate. (iii) At the within-person between-session level, a session where a trainee accurately perceived high client WA, compared to a session where the trainee accurately perceived low client WA, was followed by greater client symptom relief before the next session. In the case of estimation bias, a session where the trainee underestimated client WA was followed by greater client symptom reduction in the next session, rather than the other way around when the trainee overestimated client WA. Implications on therapist training were discussed.

(In)Congruence in Perceived Mother-child Cohesion and Informants' Depressive Symptoms: A Dyadic Response Surface Analysis.

Mother-child cohesion, reflecting the emotional connection between mothers and children, is a protective factor for individuals' mental health. The Modified Operations Triad Model suggests that children and mothers hold either congruent or incongruent views of their perceived cohesion, which reflects family functioning and is an indication of future mental health outcomes for family members. Despite increasing research on the impact of (in)congruence in perceived family functioning on children's mental health, few studies concurrently address the mental health of both mothers and children, overlooking their interdependence. This longitudinal study with multi-informant reports explored the long-term and developmental effects of (in)congruence in perceived mother-child cohesion on informants' depressive symptoms. A total of 577 families participated at the first time point, comprising 577 children (52.34% girls, Mage = 10.11 years) and 577 mothers (Mage = 37.32 years). The Dyadic Response Surface Analysis revealed that mother-child congruence at high levels of cohesion (versus low levels) predicted fewer depressive symptoms in mothers and children after three and nine months, as well as decreased depressive symptoms over nine months. Children who reported higher levels of cohesion than their mothers experienced fewer depressive symptoms after three months. Mothers with higher levels of cohesion than their children reported fewer depressive symptoms after three months. The current findings emphasize the importance of identifying and resolving discrepancies in perceived mother-child cohesion between mothers and children to promote a healthy family environment.
