Background: The COVID-19 pandemic requires massive and rapid behavior change. The Health Action Process Approach (HAPA) describes personal determinants that play a key role in behavior change. This study investigated whether these determinants are associated with adherence to physical distancing measures to prevent the spread of COVID-19 (i.e. keeping 1.5 m physical distance and staying at home). Decreased psychosocial well-being and lack of social support were explored as barriers to adherence. Methods: Two cross-sectional surveys were conducted among adults in Belgium. The first survey (N = 2,379; March 2020) focused on adherence to physical distancing measures. The second survey (N = 805; April 2020) focused on difficulty with, and perseverance in, adhering to these measures. Linear regression models were fitted to examine associations with HAPA determinants, psychosocial well-being, and social support. Results: Self-efficacy, outcome expectancies, intention, action planning, and coping planning were related to adhering to, difficulty with, and perseverance in, adhering to physical distancing measures. Decreased psychosocial well-being and lack of social support were related to more difficulties with adhering to physical distancing and lower perseverance. Conclusions: Health action process approach determinants are associated with adherence to physical distancing measures. Future work could design HAPAbased interventions to support people in adhering to these measures.

Our findings indicate that child and parental PF are resilience factors and that pain acceptance buffers the negative impact of pain intensity. Implications for psychosocial interventions that target (pain-specific) PF in children and parents are discussed.

Objective: This prospective study examined risk and resilience predictors of pain and functional recovery in the first six months after major surgery in adolescents. Methods: Adolescents with Adolescent Idiopathic Scoliosis undergoing spinal fusion surgery (n = 100, aged 12 to 18 years, 77% girls) completed assessments prior to surgery, and at three weeks, six weeks, and six months after surgery. Recovery trajectories in pain, health-related quality of life, and objectively registered physical activity were identified. Pre-surgical pain catastrophizing and pain intensity (risk), and psychological flexibility and postsurgical pain acceptance (resilience) were examined as predictors of recovery.Results: Latent growth class analyses revealed four distinct pain recovery trajectories (i.e., Severe-Moderate (11 %, n = 9), Mild-No (58%, n = 49), Moderate-Mild (24%, n = 20), and Moderate-Severe (7%, n = 6) pain trajectory), two Health-Related Quality of Life (HRQOL) recovery trajectories, two trajectories characterizing recovery in average daily physical activity at moderate-to-vigorous intensity (MVPA), and three trajectories characterizing recovery in total physical activity volume characterized by the average daily number of steps. Subsequent MANOVA analyses revealed that pre-surgical pain intensity (partial η 2 = .21, p < .001)and pain catastrophizing (partial η 2 = .13, p < .01) were both predictive of poorer recovery in HRQOL, and pain catastrophizing additionally predicted poorer pain recovery (partial η 2 = .15, p < .05). Psychological flexibility (partial η 2 = .25, p < .001) and postsurgical pain acceptance (partial η 2 = .07, p < .05) were predictive of more favorable recovery trajectories in HRQOL, and psychological flexibility additionally predicted more favorable recovery trajectories in postsurgical pain (partial η 2 = .15, p < .05). Daily MVPA trajectories were not significantly predicted by any of the hypothesized factors, while pre-surgical pain catastrophizing levels were predictive of a delayed recovery trajectory in daily amount of steps (partial η 2 = .17 p < .01). Conclusions: Pre-surgical screening could include assessment of pain intensity, pain catastrophizing, psychological flexibility, and pain acceptance to identify adolescents who are at-risk for poorer recovery. These are potentially modifiable factors that can be targeted in pre-surgical interventions to prevent poor and foster adaptive outcomes after major surgery in adolescents.

Objective This study sets out to identify potential daily antecedents and consequences of pain-related activity avoidance and engagement behavior in adolescents with chronic pain. Methods Adolescents (N = 65, Mage = 14.41) completed baseline self-reports and a diary for 14 days. Afternoon and evening reports were used to infer a network structure of within-day associations between pain intensity, pain-related fear, pain catastrophizing, affect, and pain-related activity avoidance and engagement behavior. Baseline psychological flexibility was examined as a potential resilience factor. Results Activity avoidance in the evening was predicted by pain-related fear and avoidance earlier that afternoon. Activity engagement was predicted by positive affect and activity engagement in the afternoon. Pain-related behavior in the afternoon was not related to subsequent changes in pain intensity, pain-related fear, pain catastrophizing, or affect. Pain-related fear in the afternoon was predictive of increased levels of pain and pain catastrophizing in the evening. Both pain-related fear and pain catastrophizing in the evening were predicted by negative affect in the afternoon. Psychological flexibility was associated with lower levels of daily activity avoidance and buffered the negative association between pain intensity and subsequent activity engagement. Conclusions This study provides insight into unique factors that trigger and maintain activity avoidance and engagement and into the role of psychological flexibility in pediatric pain. Future work should focus on both risk and resilience factors and examine the role of psychological flexibility in chronic pediatric pain in greater detail.

BackgroundParental behavior can influence how well adolescents cope with chronic pain. Previous research has largely focused on how parents negatively impact adolescent functioning. Yet more recent work suggests that parents – and particularly parental psychological flexibility – can foster better adolescent pain-related functioning. In this study we examined if parental protective responses and instructions to engage in activities in the presence of pain mediate the impact of parental psychological flexibility and acceptance of adolescent pain on adolescents’ daily pain-related behavior.MethodFifty-six adolescents with chronic pain (Mage = 14.5 years, 86% girls) and one of their parents (93% mothers) were recruited at initial evaluation at two pediatric pain clinics in the US. Parents completed baseline questionnaires assessing psychologically flexible parenting and acceptance of adolescent pain. Next, parents and adolescents completed a 14-day self-report diary assessing adolescent activity-avoidance and activity-engagement in the presence of pain (adolescent report), and parental protective responses and instructions for their adolescent to engage in activities (parent report).ResultsPsychologically flexible parenting and acceptance of adolescent pain in parents were indirectly related to lower daily adolescent activity-avoidance, via their negative association with daily parental protective responses. Positive associations also emerged between baseline psychologically flexible parenting and overall levels of adolescent activity-engagement via its negative association with overall levels of parental protectiveness across the 14-day period. Psychologically flexible parenting and parental acceptance of adolescent pain were also indirectly related to daily decreases in adolescent activity-avoidance via their association with daily increases in parental activity-engagement instructions. These baseline parental resilience factors were also positively related to overall levels of parental engagement instructions, a route via which an indirect association with both higher overall activity-engagement as well as higher overall activity-avoidance in the adolescent was observed.ConclusionOur findings suggest an (indirect) adaptive role of parental psychological flexibility on adolescent daily pain-related behavior via its impact on parental protective behavior. If our findings replicate, they would suggest that these parental behaviors could be targeted in pain treatments that include both adolescents and their parents. Future research could further examine the impact of parental instructions on pain-related behavior in adolescents with chronic pain.

Research on chronic pain has traditionally focused on how direct pain experiences lead to maladaptive thoughts, feelings, and actions that set the stage for, and maintain, pain-related disability. Yet the capacity for language (and more specifically verbal instructions or rules) to put people into indirect contact with pain has never been systematically investigated. In this article, we introduce a novel theoretical perspective on verbal processes and discuss how the study of verbal rules may increase our understanding of both maladaptive and adaptive functioning in chronic pain. Several useful characteristics of verbal rules and rule-following in the context of chronic pain are outlined. Future research directions and implications for clinical practice are then discussed. Perspective: This focus article argues that, by studying verbal rules and rule-following, we will gain a better understanding of (mal)adaptive functioning in the context of chronic pain. Future research directions are outlined and suggestions for improving clinical practice are considered.

To limit the spread of COVID-19, many countries, including Belgium, have installed physical distancing measures. Yet, adherence to these newly installed behavioral measures has been described as challenging and effortful. Based on the Health Action Process Approach (HAPA) model, this study performed an in-depth evaluation of when, why, and how people deviated from the physical distancing measures.An online mixed-method study was conducted among Belgian adults (N = 2055) in the beginning of May 2020. Participants were recruited via an open call through email and social media platforms, using snowball sampling. Conditions wherein people deviated from the physical distancing measures were assessed by means of an open-ended question. HAPA determinants were assessed in a quantitative way.Half of the sample reported to deviate from the measures. Further, deviation from the measures was associated with each determinant outlined by the HAPA. Findings highlight that many people deviated from the measures because of their need for social contact. The majority of the people who deviated from the measures stated that they carefully weighed the risks of their behavior.Need for social contact pushed people to deviate from physical distancing measures in a deliberate manner. Potential areas for future interventions aimed at promoting adherence to physical distancing measures and enhancing psychosocial wellbeing are discussed.

Chronic pain is a prevalent condition in youth, and the pain experience is strongly influenced by emotional processes. Studying emotion variability and regulation (ER) may help better understand pain behavior. As the development of emotion-related abilities predominantly takes place in the family context, examining ER within parent-adolescent dyads is important. We set out to test the association of parent and adolescent ER and adolescent emotional variability with adolescent pain behavior (ie, pain interference, activity avoidance, and activity engagement). A sample of 56 adolescents (M age 5 14.5, 85.7% women) with chronic pain and one of their parents (92.9% mothers) participated in this study. Adolescents completed baseline measures of average pain intensity, ER, and mean positive and negative affect. Furthermore, adolescents completed an electronic diary for 14 consecutive days, reporting on emotional state, activity avoidance, activity engagement, and pain interference. Parents completed measures of ER and their own history of pain. We performed a variable selection procedure, the least absolute shrinkage and selection operator method, to determine important predictors of adolescent pain behavior. Adolescent high positive affect was associated with more activity engagement, less pain interference, and less activity avoidance, indicating that positive affect might enhance the willingness to engage in activities in the presence of pain. Adolescent ER strategy emotional reappraisal and parents' own history of pain were predictors of less activity engagement. Parent ER was not related to adolescent ER. In conclusion, our results highlight the potential of enhancing positive affect as an intervention target for chronic pain.
