Smartphone and social network addiction in early adolescents: The role of self-regulatory self-efficacy in a pilot school-based intervention.

BACKGROUND: Youths' online problematic behaviors, such as smartphone or social network sites (SNS) addiction, gained increasing attention nowadays, due to their impact on concurrent and later adjustment, such as emotional and/or behavioral problems, academic impairments, or relational issues. AIMS: This study aims to evaluate the effectiveness of a pilot school-based intervention to contrast online addictive behaviors while fostering adolescents' self-regulative abilities. MATERIALS & METHODS: The intervention started in January 2022 in an Italian junior high school located in Rome, and consisted of four meetings with students. A total sample of 462 15-year-old adolescents (Mage = 15.2; SD = 0.50; 41% females; Ncontrol = 214; Nintervention = 248) was considered. Within the latent difference score framework, we examined short-term changes from the pre-to-the-postintervention levels of SNS and smartphone addiction, and self-regulatory self-efficacy (SRSE) beliefs as a possible booster of the intervention's effectiveness. RESULTS: Results showed a significant decrease in both online addictions (SNS and smartphone addiction), controlling for age, gender, sexual orientation, and socioeconomic status, because of the short-term efficacy of the project. The buffering effect of SRSE beliefs was further supported. CONCLUSION: These findings emphasized the usefulness of promoting youths' self-regulative beliefs to contrast problematic tendencies, according to a Positive Youth Development perspective which focused on resources rather than only on the prevention of negative outcomes for youths' adjustment.

The developmental trends of parental self-efficacy and adolescents' rule-breaking behaviors in the Italian context: A 7-wave latent growth curve study.

Parental self-efficacy (PSE) captures parents' beliefs in their ability to perform the parenting role successfully and to handle pivotal issues of specific developmental periods. Although previous studies have shown that, across the transition to adolescence, parents show decreasing levels of PSE while adolescents exhibit increasing engagement in rule-breaking (RB) behaviors, there is a paucity of studies investigating whether and how changes in PSE are related to late adolescents' RB behaviors across development. The present study examined the developmental trends of PSE among Italian mothers and fathers over seven waves (representing children's transition from late childhood to late adolescence; approximately from 9 to 18 years old) as well as the longitudinal associations between PSE and RB behaviors during late adolescence. Data were drawn from seven waves of the Parenting Across Cultures (PAC) project, a large-scale longitudinal, cross-cultural study, and included 200 Italian children (MAgeAtTime1 = 9.80, SD = 0.65; 50.5% girls) and their parents (200 mothers; 190 fathers). PSE was measured across all seven time-points (from T1 to T7), while adolescents' RB behaviors were measured at the first and last assessment (T1 and T7). Results of univariate latent growth models showed a cubic trend of mothers' PSE, which revealed a decreasing pattern characterized initially by a slight decline, followed by a rebound before continuously decreasing. By contrast, fathers' PSE followed a linear decrease over time. Finally, our findings evidenced that only the slope of mothers' PSE negatively predicted adolescents' RB behaviors at T7, implying that mothers who maintained higher levels of PSE over time had children who later engaged in lower RB behaviors. The study implications are discussed.

Predictors and outcomes associated with the growth curves of self-efficacy beliefs in regard to anger and sadness regulation during adolescence: a longitudinal cross-cultural study.

Introduction: This longitudinal study examined unique and joint effects of parenting and negative emotionality in predicting the growth curves of adolescents' self-efficacy beliefs about regulating two discrete negative emotions (anger and sadness) and the association of these growth curves with later maladjustment (i.e., internalizing and externalizing problems). Methods: Participants were 285 children (T1: M age = 10.57, SD = 0.68; 53.3% girls) and their parents (mothers N = 286; fathers N = 276) from Colombia and Italy. Parental warmth, harsh parenting, and internalizing and externalizing problems were measured in late childhood at T1, whereas early adolescents' anger and sadness were measured at T2 (T2: M age = 12.10, SD = 1.09). Adolescent self-efficacy beliefs about anger and sadness regulation were measured at five time-points from T2 to T6 (T6: M age = 18.45, SD = 0.71), and internalizing and externalizing problems were measured again at T6. Results: Multi-group latent growth curve models (with country as the grouping variable) demonstrated that in both countries there was on average a linear increase in self-efficacy about anger regulation and no change or variation in self-efficacy about sadness regulation. In both countries, for self-efficacy about anger regulation (a) T1 harsh parenting and T1 externalizing problems were negatively associated with the intercept, (b) T2 anger was negatively associated with the slope, and (c) the intercept and the slope were associated with lower T6 internalizing and externalizing problems, controlling for T1 problems. For self-efficacy about sadness regulation, (a) T1 internalizing problems were negatively associated with the intercept only in Italy, (b) T2 sadness was negatively associated with the intercept only in Colombia, and (c) the intercept negatively predicted T6 internalizing problems. Discussion: This study advances knowledge of the normative development of self-efficacy beliefs about anger and sadness regulation during adolescence across two countries, highlighting the predictive value of pre-existing family and individual characteristics on this development and prediction by the development of self-efficacy beliefs on later adjustment.

Emotion-related Self-regulation Profiles in Early Adolescence: A Cross-National Study.

Emotionality and self-regulation are crucial for positive development, especially during early adolescence when youths experience normative increases in behavioral problems and declines in prosociality. Using Latent Profile Analysis (LPA-a person-oriented technique to identify patterns of functioning within individuals), we identified youths' profiles based on dimensions of mother-reported negative emotionality (NE; anger/frustration, sadness/depressive mood), and Effortful Control (EC; attentional, activation and inhibitory control) and examined concurrent associations with self- and mother-reported aggressive and prosocial behaviors. We included a cross-national sample of 530 youths (M age =11.43; 49% males) from Colombia (17%), Italy (36%), and United States (47%). We identified four profiles: Adjusted (38%; low NE; high EC)-lowest aggression, highest prosociality; Average (34%; average NE and EC)-average aggression and prosociality; Emotional-regulated (20%; high NE; average EC)-average aggression and high prosociality; and Emotional-dysregulated (8%; high NE; low EC)-highest aggression, low prosociality. We highlight associations of different emotion-regulation patterns with specific behavioral responses in early adolescence.

Prosocial and externalizing behaviors in children raised by different-and same-gender parent families: new directions in parenting research.

Introduction: Limited research focused on the association between parenting practices and children's prosocial and externalizing behaviors comparing same- and different-gender parent families. The present study considered 76 Italian families (73% same-gender and 27% different-gender parent families) with 8-year-old (SD = 2.17; 49% assigned female at birth) children born through assisted reproductive techniques, to explore parenting practices and children's prosocial and externalizing behaviors. Method: We ran a Multiple-group-by-couple Structural Equation Model in which we estimated the predictive role of parenting on children's behaviors, controlling for age, gender, and family socioeconomic status using the Maximum Likelihood estimation. Results: Results showed that both same- and different-gender parent families reported high levels of parental warmth and very low levels of hostility and rejection; regarding children's behaviors, both same- and different-gender parent families reported high levels of prosociality and low levels of externalizing behaviors. In addition, same-gender parents reported significantly higher levels of children's prosociality and parental warmth than different-gender parents. Regarding associations between parenting practices and behaviors, we found a positive association between positive parenting practices and increasing children's prosocial behaviors and decreasing children's externalizing behaviors, in both same- and different-gender families, controlling for family background characteristics. Conclusion: The present study encourages future research to investigate how specific parenting practices can influence behavioral adjustment in children, focusing on same-gender parent families.

Pathways from Maternal Harsh Discipline Through Rumination to Anxiety and Depression Symptoms: Gender and Normativeness of Harsh Discipline as Moderators.

This study examined gender-specific longitudinal pathways from harsh parenting through rumination to anxiety and depression symptoms among early adolescents from three countries and six subgroups. Participants were 567 mothers, 428 fathers, and 566 children (T1: Mage = 10.89; 50% girls) from Medellín, Colombia (n = 100); Naples, Italy (n = 95); Rome, Italy (n = 99); Durham, North Carolina, United States (Black n = 92, Latinx n = 80, and White n = 100). Parent reported maternal and paternal harsh parenting were measured at T1. Adolescent reported rumination was measured at T2 (Mage = 12.58) and anxiety and depression symptoms were measured at T1 and T3 (Mage = 13.71). Rumination mediated the pathway from maternal harsh discipline to girls' anxiety and depression symptoms, controlling for baseline anxiety and depression symptoms. The more harsh discipline mothers used, the more their daughters ruminated, which in turn was associated with increased anxiety and depression symptoms. Exploratory moderated mediation analyses indicated that the strength of the mediational pathway from maternal harsh discipline through girls' rumination to anxiety and depression symptoms decreased as the normativeness of harsh parenting increased. Mediational pathways for boys and for paternal harsh discipline were not significant. Our findings expand knowledge on specific contexts in which rumination is a mechanism for understanding pathways to anxiety and depression symptoms.

Facing the Pandemic in Italy: Personality Profiles and Their Associations With Adaptive and Maladaptive Outcomes.

The negative impact of the COVID-19 pandemic on individuals' psychosocial functioning was widely attested during the last year. However, the extent to which individual differences are associated with adaptive and maladaptive outcomes during quarantine in Italy remains largely unexplored. Using a person-oriented approach, the present study explored the association of personality profiles, based on three broad individual dispositions (i.e., positivity, irritability, and hostile rumination) and two self-efficacy beliefs in the emotional area (i.e., expressing positive emotions and regulating anger emotion), with adaptive and maladaptive outcomes during the first Italian lockdown (March-June 2020). In doing so, we focused also on how different age groups (i.e., young adults and adults) differently faced the pandemic. The study was conducted through an online survey from May to June 2020 and included 1341 participants living in Italy, divided into two groups: 737 young adults aged 18-35 and 604 adults aged 36-60 years old. Latent Profile Analysis identified three personality profiles: resilient, vulnerable, and moderate. A subsequent path analysis model showed that the resilient profile was positively associated with prosocial behavior as an indicator of adaptive outcome, and negatively associated with three maladaptive outcomes: interpersonal aggression, depressive symptoms, and anxiety problems. Contrarily, the vulnerable profile resulted negatively associated with prosocial behavior and positively associated with the three maladaptive outcomes. Finally, regarding age group differences, young adults belonging to the vulnerable profile showed a greater association especially with interpersonal aggression, depression, and anxiety problems, as compared to adults belonging to the same profile. Overall, the results of the present study highlighted the importance to analyze individual functioning during an isolation period by using a person-oriented approach. Findings evidenced the existence of three different profiles (i.e., Resilient, Vulnerable, and Moderate) and subsequent path analysis revealed, especially for the vulnerable profile and young adults, a greater maladaptive consequence of the quarantine. The practical implications will be discussed.

The Effects of Attachment, Temperament, and Self-Esteem on Technology Addiction: A Mediation Model Among Young Adults.

Excessive use of technology has become a worldwide problem due to its high prevalence, fast growth rate, and undesirable consequences. However, little is known about underlying psychological mechanisms that maintain excessive use of technology. We investigated the mediating role of self-esteem, novelty seeking, and persistence on the relationship between attachment dimensions and technology addiction among young adults. Data were collected from 727 young adults (females, N = 478; 66.3 percent), aged 23.44 ± 3.02 years. Participants completed self-report measures of secure and insecure attachment dimensions, personality, and temperament characteristics (i.e., self-esteem, novelty seeking, and persistence), technology addiction and frequency of technology use (i.e., own technology use, perceived use by peers and parents). The mediation model was tested through a path analysis. The effects of attachment insecurity on technology addiction were partially mediated by the levels of persistence and self-esteem, whereas the effects of attachment security on technology addiction were fully mediated. The effects remained robust even after controlling for the frequency of technology use. The model was gender and age invariant, suggesting that the mediation worked in a similar way for both men and women and across ages. Findings suggest that attachment dimensions exert not only a direct but also an indirect effect on technology addiction through self-esteem and persistence. Such findings may help to develop psychosocial interventions that are sensitive to young adults' attachment, personality, and temperament characteristics.

Negative Parenting, Adolescents' Emotion Regulation, Self-Efficacy in Emotion Regulation, and Psychological Adjustment.

This study examines associations between parents' rejection and control, adolescents' self-efficacy in their regulation of negative emotions, and maladjustment. Path analyses were employed to test (a) whether adolescents' dysregulation and self-efficacy regarding anger/sadness regulation mediate the relationship between parental rejection/control and adolescent maladjustment; (b) whether adolescent adjustment mediates the association between parental rejection/control and dysregulation and self-efficacy regarding anger/sadness regulation. Participants included 103 Italian adolescents (Time 1: M age = 15.57; 53% male), their mothers (n = 103), and their fathers (n = 79). Follow up data were assessed one year later (Time 2). At Time 1, adolescent reports of the frequency of mothers' and fathers' rejection and control were examined. At Time 2, adolescent-reports of their beliefs about self-efficacy in regulating anger and sadness, as well as anger and sadness dysregulation, were assessed by two methods: questionnaire and mobile ecological momentary assessment. At Time 2, mothers', fathers', and adolescents' reports of adolescents' aggressive behaviors and depressive problems were also assessed. Maternal rejection was associated with higher one year later aggressive problems, which in turn were associated with higher dysregulation of sadness, and lower self-efficacy in dealing with both anger and sadness. In addition, maternal rejection was associated with higher depressive symptoms one year later, which in turn were associated with lower self-efficacy in dealing with sadness and higher dysregulation of both anger and sadness. Finally, maternal control was associated with higher depressive symptoms, whereas paternal control was associated with lower depressive symptoms.

Development of internalizing symptoms during adolescence in three countries: the role of temperament and parenting behaviors.

This longitudinal study examined the unique and joint effects of early adolescent temperament and parenting in predicting the development of adolescent internalizing symptoms in a cross-cultural sample. Participants were 544 early adolescents (T1: Mage = 12.58; 49.5% female) and their mothers (n = 530) from Medellín, Colombia (n = 88), Naples, Italy (n = 90), Rome, Italy (n = 100) and Durham, North Carolina, United States (African Americans n = 92, European Americans n = 97, and Latinx n = 77). Early adolescent negative emotionality (i.e., anger and sadness experience), self-regulation (i.e., effortful control), and parent monitoring and psychological control were measured at T1. Adolescent internalizing symptoms were measured at three time points. Latent Growth Curve Modeling (LGCM) without covariates or predictors indicated a slight linear increase in internalizing symptoms from ages 13-16 years across nearly all cultural groups. Multi-group LGCMs demonstrated several paths were consistently invariant across groups when examining how well temperament and parenting predicted intercept and slope factors. Higher initial levels of internalizing symptoms were significantly predicted by higher adolescent negative emotionality and parental psychological control as well as lower adolescent effortful control and parental monitoring measured one year earlier. Overall, adolescent effortful control appeared to protect against the emergence of internalizing symptoms in all cultures, but this effect faded over time. This study advances knowledge of the normative development of internalizing symptoms during adolescence across cultures while highlighting the predictive value of early adolescent temperament and parenting.

Perception of school climate, academic performance and risk behaviors in adolescence.

Previous studies support the relevance of students' perception of positive and negative school climate to learning processes and adolescents' adjustment. School climate is affected by both the interactions that are established within the classroom, and by the teachers' behaviors. This study has the overall objective of investigating the relationship between the perception of positive and negative school climate and students' (mal)adjustment during adolescence. Participants were 105 Italian adolescents (52.5% boys, mean age = 15.56, SD = .77) who responded for 15 consecutive days (ecological momentary assessment) to questions related to their perception of positive and negative school climate (Time 1). After one year (Time 2), students' academic performance reported by mothers and fathers and adolescents' self-reported propensity to engage in risk behaviors were examined. Four hierarchical regression models were implemented considering the mean and the instability levels (RMSSD) of the perception of positive and negative school climate as independent variables and, respectively, academic performance and risk behaviors as dependent variables. Results suggest that a higher perception of positive school climate and its instability predict higher academic performance one year later, while a higher perception of negative school climate and its instability predict higher risk behaviors. This study provides an innovative perspective to reflect on the relationship between students' perceptions of school climate and adolescents' (mal)adjustment.

Perceived Similarity to Gender Groups Scale: Validation in a Sample of Italian LGB + and Heterosexual Young Adults.

Introduction: The present article describes two interrelated studies that examine gender typicality in young adulthood using a new dual-identity approach. Methods: Participants were recruited online from March 2020 to February 2021 and reported their perceived similarity to own- and other-gender peers as a way to assess their gender typicality. In study 1, the authors conducted an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA) to test and validate the Perceived Similarity to Gender Groups Scale in a sample of Italian young adults (n = 571; M age = 23.9; SD = 3.60). The authors documented the configural, metric, scalar measurement invariance, and validity. In study 2, the Perceived Similarity to Gender Groups Scale adopted in study 1 was used to assess the distribution of different typologies of gender typicality in another sample of Italian young adults who vary in gender and sexual orientation (n = 1126; M age = 24.3; SD = 3.51). Results: Results confirmed the structural validity of the Perceived Similarity to Gender Groups Scale, revealing the two-factor structure of the scale. Moreover, results of cluster analysis found different typologies of self-perceptions of gender typicality. Conclusion: Both studies emphasize the relevance of studying gender typicality in young adulthood through a dual-identity approach, highlighting the relevance of gender and sexual orientations. Policy Implications: The use of the dual-identity approach has significant social and clinical implications as it represents a more flexible and representative model of the complexity of gender typicality.

Exploring the Protective Function of Positivity and Regulatory Emotional Self-Efficacy in Time of Pandemic COVID-19.

Despite several empirical studies on the 2019 coronavirus disease (COVID-19) pandemic that have highlighted its detrimental effect on individuals' mental health, the identification of psychological factors that may moderate its impact on individuals' behavior and well-being remains partly unexplored. The present study was conceived to examine the mediation role of regulatory emotional self-efficacy in the relationship between positivity and anxiety, depression, and perceived self-efficacy in complying with the containment measures to contrast the COVID-19 spread. Furthermore, the moderation role of age was tested. A sample of 1258 participants (64.2% women; Mage = 42.09, SD = 13.62) enrolled from the Italian general population answered an online survey aimed at investigating the role of individual differences in facing the COVID-19 pandemic. We opted for a snowball recruiting procedure to find participants. The online survey was disseminated through email invitation and using social media platforms (i.e., Facebook, Instagram). A multi-group path analysis model was performed using Mplus 8.4 to explore the hypothesized relations among variables. The following criteria were employed to evaluate the goodness of fit: χ2 likelihood ratio statistic, CFI and TLI > 0.95, RMSEA < 0.06 and SRMR < 0.08. The findings corroborated the protective role of both positivity and regulatory emotional self-efficacy in reducing individuals' anxiety and depressive symptoms, as well as in fostering individuals' capabilities in complying with the containment measures imposed by the government to reduce the risk of illness and to contain the spread of the virus COVID-19. Specifically, regulatory emotional self-efficacy beliefs partially mediated the relations between positivity and anxiety and depressive symptoms and fully mediated the effect of positivity on perceived self-efficacy beliefs in complying with the containment measures. These paths were equal across ages. The results of the present study appear relevant to implementing psychological interventions aimed to reduce the deleterious effects of the COVID-19 pandemic on mental health through the promotion of individuals' optimistic orientation and emotion regulation.

Maternal and paternal psychological control and adolescents' negative adjustment: A dyadic longitudinal study in three countries.

Psychological Control (PC) interferes with autonomy-related processes in adolescence and has a negative impact on adolescents' development related to internalizing and externalizing problems. Several scholars suggested that PC can be used differently by mothers and fathers. However, these differences are still understudied and mainly grounded on maternal and/or adolescents' perspectives, leading to potentially incomplete inferences on the effects of PC. The present study extends previous research on PC in two directions. First, we tested the dyadic and cumulative effects of maternal and paternal PC on adolescents' antisocial behaviors and anxious-depressive symptoms. Secondly, we explored the cross-cultural generalizability of these associations in three countries: Italy, Colombia, and USA. Participants included 376 families with data from three consecutive years (T1, adolescents' age = 13.70). Mothers' and fathers' reports of PC and youth's reports of antisocial and internalizing behaviors were assessed. Using the Actor-Partner Interdependence Model (APIM) we found that maternal PC predicted adolescents' reported antisocial behaviors whereas paternal PC predicted lower anxious-depressed symptoms. Comparisons across countries evidenced the cross-cultural invariance of the longitudinal APIM across Italy, Colombia, and USA. The practical implications of these results are discussed.

Disentangling Italian mothers' and fathers' psychological control over time: A random-intercept cross-lagged panel model.

Psychological Control (PC) refers to the control parents exert over their offspring through strategies that limit the psychological and emotional experience of children and adolescents. Although the topic of PC has been largely investigated in the literature, very little is known on the potential differences/similarities in the use of specific psychologically controlling strategies by mothers and fathers. Hence, in the present study, we considered the contribution of both parents to analyze the direct and mutual relations in the use of PC over time by disentangling the role of mothers and fathers at the between- and within-person level. Participants were 147 parents of Italian adolescents (mean age = 13.54 at Time 1) who reported on their use of two different PC dimensions: Relationship-Oriented PC (R-OPC) and Verbal Constraint (VC). Results from a Random-Intercept Cross-Lagged Panel Model showed that at the between-person level, mothers' and fathers' use of R-OPC (and VC) was positively correlated over time. At the within-person level, significant cross-lagged effects showed that one parent's higher than usual levels of R-OPC and VC positively predicted the other parent's higher than usual use of PC at the next time point, showing how parental variations in PC are related to their partner's variations over time. For VC, significant cross-lagged effects were found only for fathers. Furthermore, differences were found when comparing the classical cross-lagged panel models to the Random-Intercept Cross-Lagged Panel Models.

Longitudinal associations between mothers' and fathers' anger/irritability expressiveness, harsh parenting, and adolescents' socioemotional functioning in nine countries.

The present study examines parents' self-efficacy about anger regulation and irritability as predictors of harsh parenting and adolescent children's irritability (i.e., mediators), which in turn were examined as predictors of adolescents' externalizing and internalizing problems. Mothers, fathers, and adolescents (N = 1,298 families) from 12 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and United States) were interviewed when children were about 13 years old and again 1 and 2 years later. Models were examined separately for mothers and fathers. Overall, cross-cultural similarities emerged in the associations of both mothers' and fathers' irritability, as well as of mothers' self-efficacy about anger regulation, with subsequent maternal harsh parenting and adolescent irritability, and in the associations of the latter variables with adolescents' internalizing and externalizing problems. The findings suggest that processes linking mothers' and fathers' emotion socialization and emotionality in diverse cultures to adolescent problem behaviors are somewhat similar.

Daily Associations between Emotions and Aggressive and Depressive Symptoms in Adolescence: The Mediating and Moderating Role of Emotion Dysregulation.

Nearly half of adolescents experience depressive or aggressive symptoms that impair their functioning at some point in adolescence. Experiencing intense difficult emotions and difficulties regulating such emotions may lead to these depressive and aggressive symptoms. However, existing work largely investigates how adolescent emotions at a single time point predict adolescent depressive or aggressive symptoms months or years later. New investigations are needed to capture the dynamic, changing nature of adolescents' daily experiences of emotions and symptoms of mental distress. Such investigations would further understanding of how emotions affect mental health in adolescents' everyday lives. Answering this call, the present study investigated how emotion dysregulation moderated and mediated daily associations between sadness and depressive symptoms and between anger and aggression utilizing ecological momentary assessment in a community sample of 103 Italian adolescents (Mage = 16.77, SD = 0.78, range: 15-18 years old; 47% female). The results revealed that if an adolescent experienced higher-than-usual sadness or anger on a particular day, then they also experienced higher than usual depressive or aggressive symptoms, respectively. Emotion dysregulation mediated and moderated these associations. Adolescents with higher anger had greater difficulties regulating their anger, which led to higher aggressive symptoms (a mediating effect). If adolescents' sadness was higher than usual on a given day, their depressive symptoms were more severe than usual if they also had higher than usual difficulties regulating sadness (a moderating effect). These findings contribute to our understanding of how emotions impact mental distress on a daily basis for adolescents, emphasize the importance of examining specific adolescent emotions, and shed new light on how emotional regulatory capacities influence emotions and mental health in adolescents' everyday lives.

Longitudinal relation between state-trait maternal irritability and harsh parenting.

According to Belsky's process model of parenting, parents' personality represents the most important factor influencing parenting and child development. While an extensive literature has empirically corroborated the role of irritability traits in predicting aggressive behaviors in laboratory-based studies, only a few studies have examined the role of irritability in predicting aggressive behaviors within family contexts. The present study addressed this gap by examining the longitudinal association between maternal irritability and harsh parenting. Referencing latent state-trait theory (LST), first we estimated the amount of variance in mothers' irritability due to trait and state components, and, next, we examined the relation between mothers' irritability (both at trait- and state- levels) and harsh parenting over time. A sample of 204 mothers from Naples and Rome provided data over 5 years in four waves. Mothers averaged 40.30 years (SD = 5.33) at Time 1 and 44.01 years (SD = 5.43) at Time 4. Their children (50% girls) were 9.45 years (SD = 0.74) at Time 1 and 13.18 years (SD = 0.66) at Time 4. Results of LST analysis showed that, on average, 39% of variability in irritability was due to trait-like factors and only 12% to state-like factors. A multitrait-multistate model revealed that the irritability trait associated with mother's lack of control predicted her harsh parenting 1-year later, while controlling for the rank-order stability of harsh parenting.
