Abstract [en]

Background: Given the high prevalence and negative impact of psychological problems during adolescence, examining transdiagnostic factors that may have scope to positively influence a variety of psychological problems is imperative. The main purpose of this study was to investigate the longitudinal relationship between rumination and psychological distress and whether sleep mediated this relationship over a 2 year period.

Methods: Participants were 1620 high school students in the 7th and 8th grade at baseline from 17 public schools in three middle Sweden communities. Students completed questionnaires at school during the spring of 2014, 2015 and 2016. Rumination and psychological distress were self-reported, and sleep duration was calculated from reported bed-times, wake-times and sleep onset latencies.

Results: Sleep duration declined with age, whereas rumination and psychological distress increased. Rumination was predictive of future psychological distress and distress at a given time was predictive of concurrent rumination. Sleep duration did not consistently mediate the reciprocal relationships between rumination and psychological distress over time.

Limitations: Stronger longitudinal associations may have been obtained by using smaller measurement intervals or further delineation of outcome constructs.

Conclusions: Reducing rumination, rather than targeting sleep patterns, may work towards preventing the development of a number of psychological problems and is a strategy anticipated to function across disorders to improve young people's mental wellbeing.

Abstract [en]

Background and aims: Among chronic pain patients who are referred to participation in a multimodal rehabilitation program (MMRP), pain catastrophizing and dysfunctional pain coping is common. In many cases it may have driven the patient to a range of unsuccessful searches for biomedical explanations and pain relief. Often these efforts have left patients feeling disappointed, hopeless and misunderstood. The MMRP process can be preceded by a multimodal investigation (MMI) where an important effort is to validate the patient to create a good alliance and begin a process of change towards acceptance of the pain. However, whether the MMI has such therapeutic effect is unclear. Using a repeated single case experimental design, the purpose of this study was to investigate the therapeutic effect of MMI by studying changes in patients' experience of validation, alliance, acceptance of pain, coping, catastrophizing, and depression before and during the MMI process.

Methods: Participants were six chronic pain patients with high levels of pain catastrophizing (>25 on the Pain Catastrophizing Scale) and risk for long term disability (>105 on the Örebro Musculoskeletal Pain Screening Questionnaire) who were subjected to MMI before planned MMRP. For each patient, weekly self-report measures of validation, alliance and acceptance of pain were obtained during a 5-10-weeks baseline, before the MMI started. Subsequently, these measures were also obtained during a 6-8 weeks MMI process in order to enable comparative analyses. Additionally, pain coping, depression and pain catastrophizing were measured using standardized questionnaires before and after the MMI.

Results: Irrespective of experiences of validation and alliance before MMI, all six patients felt validated and experienced a good alliance during MMI. Acceptance of pain improved only in one patient during MMI. None of the patients showed clinically relevant improvement in pain coping, depression or catastrophizing after the MMI.

Conclusions: The patients did not change their acceptance and pain coping strategies despite of good alliance and experience of validation during the MMI process. Even if the design of this study precludes generalization to chronic pain patients in general, the results suggest that MMI may not have a therapeutic effect.

Abstract [en]

OBJECTIVES: This systematic review aimed to identify and evaluate prognostic factors for long-term (≥6 mo) physical functioning in patients with chronic musculoskeletal pain following multidisciplinary rehabilitation (MDR).

MATERIALS AND METHODS: Electronic searches conducted in MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science, and Cochrane CENTRAL revealed 25 original research reports, published 1983-2016, (n=9436). Potential prognostic factors relating to initial pain and physical and psychological functioning were synthesized qualitatively and quantitatively in random effects meta-analyses. The level of evidence (LoE) was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE).

RESULTS: Pain-related factors (intensity and chronicity) were not associated with function/disability at long-term follow-up, odds ratio (OR)=0.84; 95% confidence interval (CI), 0.65-1.07 and OR=0.97; 95% CI, 0.93-1.00, respectively (moderate LoE). A better function at follow-up was predicted by Physical factors; higher levels of initial self-reported functioning, OR=1.07; 95% CI, 1.02-1.13 (low LoE), and Psychological factors; low initial levels of emotional distress, OR=0.77; 95% CI, 0.65-0.92, low levels of cognitive and behavioral risk factors, OR=0.85; 95% CI, 0.77-0.93 and high levels of protective cognitive and behavioral factors, OR=1.49; 95% CI, 1.17-1.90 (moderate LoE).

DISCUSSION: While pain intensity and long-term chronicity did not predict physical functioning in chronic pain patients after MDR, poor pretreatment physical and psychological functioning influenced the prognosis negatively. Thus, treatment should further target and optimize these modifiable factors and an increased focus on positive, psychological protective factors may perhaps provide an opening for yet untapped clinical gains.

Abstract [en]

BACKGROUND AND OBJECTIVES: Stress and stress-related mental health complaints are common and increasing among adolescents, especially girls. Identifying typical sources of stress as well as central intervention targets is an important effort in the development of effective prevention and treatment protocols. This study investigated worry as potential mediator in the development of mental health problems in response to common stressors in adolescence. We also examined to what sources adolescents ascribe their stress over the years from the 7th through the 9th grade.

DESIGN: Prospective cohort study.

METHODS: Self-reported subjective stressor load, worry, anxiety and depressive symptoms were assessed in a sample of Swedish 7th graders (N = 1137; 46% girls, mean age 13.2) with follow-up assessments one and two years later.

RESULTS: School was the most common source of stress across all time-points, with girls reporting considerable more stress than boys. Worry mediated the relationship between overall stressor load and depressive symptoms and anxiety over time and was not moderated by gender.

CONCLUSIONS: Worry may be an important target in stress prevention and efforts to prevent stress-related problems would benefit from focusing on early adolescence as especially school stress is already relatively common in grade 7.

Abstract [en]

Background: Chronic pain patients frequently suffer from psychological symptoms. There is no consensus concerning the prevalence of severe anxiety and depressive symptoms and the strength of the associations between pain intensity and psychological distress. Although an important aspect of the clinical picture is understanding how the pain condition impacts life, little is known about the relative importance of pain and psychological symptoms for individual's life impact. The aims of this study were to identify subgroups of pain patients; to analyze if pain, psychological distress, and life impact variables influence subgrouping; and to investigate how patients in the subgroups benefit from treatments.

Methods: Background variables, pain aspects (intensity/severity and spreading), psychological distress (depressive and anxiety symptoms), and two life impact variables (pain interference and perceived life control) were obtained from the Swedish Quality Registry for Pain Rehabilitation for chronic pain patients and analyzed mainly using advanced multivariate methods.

Results: Based on >35,000 patients, 35%-40% had severe anxiety or depressive symptoms. Severe psychological distress was associated with being born outside Europe (21%-24% vs 6%-8% in the category without psychological distress) and low education level (20.7%-20.8% vs 26%-27% in the category without psychological distress). Dose relationships existed between the two psychological distress variables and pain aspects, but the explained variances were generally low. Pain intensity/severity and the two psychological distress variables were significantly associated (R-2 =0.40-0.48; P>0.001) with the two life impact variables (pain interference and life control). Two subgroups of patients were identified at baseline (subgroup 1: n=15,901 16,119; subgroup 2: n=20,690-20,981) and the subgroup with the worst situation regarding all variables participated less in an MMRP (51% vs 58%, P<0.001) but showed the largest improvements in outcomes.

Conclusion: The results emphasize the need to assess both pain and psychological distress and not take for granted that pain involves high psychological stress in the individual case. Not all patients benefit from MMRP. A better matching between common clinical pictures and the content of MMRPs may help improve results. We only partly found support for treatment resistance in patients with psychological distress burden.

Abstract [en]

Background: Recurring vulvovaginal pain is common, with evident effects on affected women's lives. Little is known about how affected women cope with painful sexual activities and how coping relates to pain intensity and psychosexual functioning over time. This prospective study explored the impact of avoidance and endurance on sexual function over time. Additionally, patterns of coping were studied on an individual level to increase knowledge about coping and its relation to psychosexual functioning.

Methods: One hundred and seventeen women, 18-35years old, with recurring vulvovaginal pain answered questionnaires at two measurement points, five months apart, assessing avoidance and endurance coping, pain intensity and psychosexual functioning. A multiple regression model explored the predictive value of avoidance and endurance on sexual function over time. Cluster analyses investigated patterns of coping and stability within the clusters. These subgroups were compared on psychosexual outcomes.

Results: Avoidance at baseline was the only significant predictor of sexual function five months later. Distinct and stable subgroups with different patterns of coping were identified, where avoidance and endurance coping were used both separately and combined. Women who both avoided and endured had the most unfavourable outcomes in terms of psychosexual functioning.

Conclusions: Avoidance of sexual activities was related to reduced sexual function over time, which calls for attention and clinical interventions targeting avoidance. Additionally, women who both avoid and endure sexual activities despite pain possibly need tailored interventions, as women with this coping pattern reported the lowest levels of psychosexual functioning.

Significance: In this prospective study, avoidance of sexual activities predicted sexual function over time, when controlling for pain intensity. Subgroups of women using distinct patterns of coping were identified. Those who both avoided and endured had the lowest levels of psychosexual functioning.

Abstract [en]

Background and aims: Irritable bowel syndrome (IBS), is a common multifactorial gastrointestinal disorder linked to disturbances in the microbe gut-brain axis. Cognitive behavioral therapy (CBT), in face-to-face format has showed promising results on IBS and its associated psychological symptoms. The present study explored for the first time if CBT for IBS affects the autonomic nervous system (ANS) during experimentally induced visceral pain and cognitive stress, respectively. The levels of state and trait anxiety, current and perceived stress were also evaluated.

Methods: In this uncontrolled trial, individual CBT was performed in face-to-face format for 12 weeks in 18 subjects with IBS. Heart rate variability and skin conductance were measured during experimentally induced visceral pain and during a cognitive task (Stroop color-word test), before and after intervention. The levels of state and trait anxiety as well as self-rated current and perceived stress were also measured before and after the intervention.

Results: CBT did not affect ANS activity during experimentally induced visceral pain and cognitive stress. The sympathetic activity was high, typical for IBS and triggered during both visceral pain and cognitive stress. The levels of state and trait anxiety significantly decreased after the intervention. No significant changes in self-rated current or perceived stress were found.

Conclusions: Results suggest that face-to-face CBT for IBS improved anxiety- a key psychological mechanism for the IBS pathophysiology, rather than the autonomic stress response to experimentally induced visceral pain and cognitive stress, respectively.

Abstract [en]

Background: Stressor experience is an important topic of research concerning adolescent health and ill-health. For this, valid and reliable measures of adolescent stress are needed. The Adolescent Stress Questionnaire 2 was developed to tap into stressor domains specific for adolescence. Psychometric evaluations in Australian and European samples have indicated adequate psychometric properties. However, the ASQ-2 is quite extensive, which may render its use in large cohort studies, where several aspects of adolescent health are investigated, inconvenient and problematic.

Objective: To evaluate the psychometric properties of a short version of the ASQ-2 (ASQ-S) in terms of construct validity and factorial invariance across gender.

Method: The ASQ-2 was translated into Swedish and items were retained from nine of the ten scales based on factor loadings. One scale (stress of emerging adult responsibilities) was removed entirely due to low internal consistency and variance explained. The remaining 27 items were piloted and then included in an ongoing 5-year longitudinal study involving the participation of all students in the 7th and 8th grade in public schools from three Swedish municipalities (N = 2768, 47.5 % girls, mean age 13.64 years). For this study data from the first and second wave was used.

Results: A nine factor Confirmatory Factor Analysis (CFA) showed a good fit to the data and invariance across sexes was supported. The nine scales correlated positively with depressive symptoms, anxiety and worry and negatively with self-esteem. Girls reported higher stress levels than boys in eight of the nine scales. Stressors related to peer pressure predicted reported levels of anxiety and worry one year later, whereas stressors related to romantic relationships predicted depressive symptoms.

Conclusions: Overall this study suggests that the ASQ-S could be a valid measure of adolescent stressor experience and psychometrically equivalent to the full ASQ-2.

Abstract [en]

Previous research has indicated that cognitive emotion regulation strategies contribute to the development and maintenance of emotional problems in adults and adolescents. However, there is a lack of longitudinal research with adolescent samples, hence knowledge of exactly how these strategies influence the development of emotional problems in adolescence is sparse. This study investigated maladaptive cognitive emotion regulation (cognitive avoidance and repetitive negative thinking) as a potential mediator in the development of anxiety and depressed mood over time in adolescence. Self-reported depressed mood, anxiety, and cognitive emotion regulation strategies were assessed during school hours in a sample of Swedish 10th graders (N=149; 53% girls), with follow-up assessments one and two years later. Repetitive negative thinking and cognitive avoidance formed a unidimensional factor of cognitive emotion regulation. Cognitive emotion regulation was found to mediate the development of both anxiety and depressed mood over time, lending support to the previous findings that cognitive emotion regulation strategies such as cognitive avoidance and repetitive negative thinking might act as transdiagnostic mechanisms in the development of emotional symptoms in adolescence. This suggests that maladaptive forms of cognitive emotion regulation could be important targets in prevention and treatment of emotional problems in adolescence.

Abstract [en]

Technology use has been the focus of much concern for adolescents' sleep health. However, few studies have investigated the bidirectional association between sleep duration and time spent using technology. The aim of this study was to test whether time spent using technology predicted shorter sleep duration, and/or vice versa using cross-lagged analyses over one year. Participants were 1620 high school students in the 8th and 9th grade at baseline from 17 public schools in three middle Sweden communities. Students completed questionnaires at school during the spring of 2015 and 2016. Time spent using technology was self-reported and sleep duration was calculated from reported bed-times, wake-times and sleep onset latency. Time spent using technology significantly predicted shorter subsequent sleep duration and vice versa. Public health advocates educating others about the negative impacts of technology on sleep must also be mindful of the opposite, that many young people may turn to technological devices when experiencing difficulty sleeping.
