Mental health and professional outcomes in parents of children with chronic kidney disease.

BACKGROUND: This study evaluated parenting stress, anxiety, and depression symptoms and their associated factors in parents of children with chronic kidney disease (CKD). METHODS: This cross-sectional study compared parents of patients with CKD (0-18 years) with a matched control group of parents of healthy children. Both groups completed the Parenting Stress Index - Short Form, the Hospital Anxiety and Depression Scale, and a sociodemographic questionnaire. RESULTS: The study group consisted of 45 parents (median age 39; 32 mothers) of CKD patients (median age 8; 36% female). Nearly 75% of children had CKD stages 2, 3, or 4, and 44.5% had congenital anomaly of the kidney and urinary tract. Five children (11%) were on dialysis, and 4 (9%) had a functioning kidney graft. Compared with parents of healthy children, more stress and anxiety symptoms were reported. Since the CKD diagnosis, 47% of parents perceived a deterioration of their own health, and 40% reduced work on a structural basis. Higher levels of stress, anxiety, and depression symptoms were associated with a more negative perception of own health, and more child medical comorbidities and school absence. CONCLUSIONS: This study showed higher levels of parenting stress and anxiety symptoms in parents of children with CKD compared with parents of healthy children. This was associated with a less positive perception of their own health, especially if the child had more medical comorbidities or more absence from school. Psychosocial interventions to reduce the parental burden should be integrated in the standard care of pediatric nephrology departments.

Protocol of identical exercise programs with and without specific breathing techniques for the treatment of chronic non-specific low back pain: randomized feasibility trial with two-month follow-up.

BACKGROUND: Chronic low back pain (CLBP) is a leading cause of disability globally. Exercise therapies are one of the commonly prescribed treatment options for CLBP. The specific exercise therapies for CLBP most commonly target movement dysfunction, but seldom brain-based pain modulation. Exercise therapies with specific breathing techniques (SBTs) have been shown to influence and enhance brain-based structural and functional pain modulation. AIMS AND OBJECTIVES: To assess the feasibility of the SBTs protocol, eligibility criteria, randomization, and dropout rates. To quantify the changes in patient outcome measures and choose the most relevant measure for larger-scale study. To quantify self-adherence levels to home exercise and monitor and record possible pain medication and other treatment modality usage, and adverse events during exercise. DESIGN: A parallel randomised analyst-blinded feasibility trial with two-month follow-up. OUTCOME MEASURES: Feasibility related to aims and objectives. Multiple pain- and health-related patient-reported outcome measures of pain intensity, disability, central sensitization, anxiety, kinesiophobia, catastrophising, self-efficacy, sleep quality, quality of life, and health and well-being status. Exercise adherence, pain medication and other treatment modality usage, and possible adverse events related to exercises will be monitored and recorded. METHODS: Thirty participants will be randomized to movement control exercise with SBTs (15 subjects in experimental group) or movement control exercise without SBTs (15 subjects in control group) in private chiropractic practice setting with two-month follow-up. Trial registration number; NCT05268822. DISCUSSION: The clinical difference in effectiveness between practically identical exercise programs in uniform study settings with or without SBTs has not been studied before. This study aims to inform feasibility and help determine whether progression to a full-scale trial is worthwhile.

Validity and reliability of the Dutch version of the PedsQL™ 3.0 End Stage Renal Disease Module in children with chronic kidney disease in Belgium.

BACKGROUND: Children with chronic kidney disease (CKD) have a low quality of life (QoL). The PedsQL™ 4.0 Generic Core Scales are widely used to assess general QoL in children. The aim of this cross-sectional study was to translate the original version of the CKD-specific PedsQL™ 3.0 End Stage Renal Disease Module into a Dutch version and to evaluate its validity and reliability. METHODS: The forward-backward translation method based on the guidelines from the original developer was used to produce the Dutch version of the PedsQL™ 3.0 ESRD Module. Fifty-eight CKD patients (aged 8-18 years) and their parents (n = 31) filled in both generic and disease-specific modules. The non-clinical control group consisted of the same number of healthy children (matched for gender and age) and their parents. RESULTS: Cronbach's alpha coefficients (α's) for the PedsQL™ 3.0 ESRD Module demonstrated excellent reliability for the Total Scale scores. For all 7 subscales, α's were greater than 0.60, except for Perceived Physical Appearance. Overall, intercorrelations with the PedsQL™ 4.0 Generic Core Scales were in the medium to large range, supporting construct validity. Parent proxy reports showed lower generic QoL for all domains in CKD patients compared to healthy children. Child self-reports only demonstrated lower QoL on the domain School Functioning in children with CKD compared to healthy children. CONCLUSIONS: This study shows good validity and reliability for the Dutch version of the PedsQL™ 3.0 ESRD Module. However, testing with a larger study group is recommended in order to make final conclusions about the psychometric qualities of this measure. A higher resolution version of the Graphical abstract is available as Supplementary information.

Preferred Self-Administered Questionnaires to Assess Resilience, Optimism, Pain Acceptance, and Social Support in People with Pain: A Modified Delphi Study.

OBJECTIVES: The plethora of self-administered questionnaires to assess positive psychosocial factors complicates questionnaire selection. This study aimed to identify and reach consensus on the most suitable self-administered questionnaires to assess resilience, optimism, pain acceptance and social support in people with pain. DESIGN: A three-round modified Delphi study. PARTICIPANTS: Forty international experts. METHODS: In Round 1, the experts suggested questionnaires deemed appropriate to assess resilience, optimism, pain acceptance and/or social support. In Round 2, experts indicated whether they considered the suggested questionnaires to be suitable (Yes/No/Don't know) to assess these psychosocial factors, taking into consideration content, feasibility, personal experience and the measurement properties which we provided for each questionnaire. Questionnaires that were considered suitable by the majority of experts (≥60%) were retained for Round 3. In Round 3, the suitability of each questionnaire was rated on a 0-10 Likert scale. Consensus was reached if ≥75% of experts rated the questionnaire ≥7. RESULTS: From the 67 questionnaires suggested in Round 1, one questionnaire could be recommended per domain. For resilience: Pain Resilience Scale; for optimism: Revised Version of the Life Orientation Test; for pain acceptance: 8-item and Revised Versions of the Chronic Pain Acceptance Questionnaire; for social support: Emotional Support Item Bank of the PROMIS tool. Consensus for these questionnaires was also reached in a sensitivity analysis which excluded the ratings of experts involved in the development, translation and/or validation of relevant questionnaires. CONCLUSION: We advocate the use of these recommended questionnaires so data can be compared and pooled more easily.

[Pediatric pain treatment and prevention for hospitalized children]. / Pädiatrische Schmerztherapie und -prävention bei hospitalisierten Kindern.

INTRODUCTION: Prevention and treatment of pain in pediatric patients compared with adults is often not only inadequate but also less often implemented the younger the children are. Children 0 to 17 years are a vulnerable population. OBJECTIVES: To address the prevention and treatment of acute and chronic pain in children, including pain caused by needles, with recommended analgesic starting doses. METHODS: This Clinical Update elaborates on the 2019 IASP Global Year Against Pain in the Vulnerable "Factsheet Pain in Children: Management" and reviews best evidence and practice. RESULTS: Multimodal analgesia may include pharmacology (eg, basic analgesics, opioids, and adjuvant analgesia), regional anesthesia, rehabilitation, psychological approaches, spirituality, and integrative modalities, which act synergistically for more effective acute pediatric pain control with fewer side effects than any single analgesic or modality. For chronic pain, an interdisciplinary rehabilitative approach, including physical therapy, psychological treatment, integrative mind-body techniques, and normalizing life, has been shown most effective. For elective needle procedures, such as blood draws, intravenous access, injections, or vaccination, overwhelming evidence now mandates that a bundle of 4 modalities to eliminate or decrease pain should be offered to every child every time: (1) topical anesthesia, eg, lidocaine 4% cream, (2) comfort positioning, eg, skin-to-skin contact for infants, not restraining children, (3) sucrose or breastfeeding for infants, and (4) age-appropriate distraction. A deferral process (Plan B) may include nitrous gas analgesia and sedation. CONCLUSION: Failure to implement evidence-based pain prevention and treatment for children in medical facilities is now considered inadmissible and poor standard of care.

Families with pediatric type 1 diabetes: A comparison with the general population on child well-being, parental distress, and parenting behavior.

AIMS: The aim of this study was to compare families with a child (2-12 years) with type 1 diabetes (T1D) to families which are not confronted with chronic illness, with regard to children's well-being, parental distress, and parenting behavior. In addition, differences were explored between families whose child has optimal vs suboptimal glycemic control. METHODS: Mothers, fathers, and children of 105 families with pediatric T1D completed questionnaires assessing child well-being, parental distress, and parenting. The control group consisted of 414 families without chronic illness. RESULTS: With regard to child well-being, children with T1D had more adjustment difficulties (as reported by mothers) and lower quality of life (QoL) (as reported by mothers and fathers), whereas children themselves (8-12 years) reported higher QoL compared to controls. In terms of parental distress, mothers, but not fathers, of children with T1D reported more stress, anxiety symptoms, and depressive symptoms than controls. With regard to parenting behavior, parent reports revealed less protectiveness in fathers and less autonomy support and responsiveness in both parents as compared to controls. No differences were found in parent-reported psychological control between parents of children with and without T1D, but children with T1D perceived lowered parental psychological control. Lastly, secondary analyses indicated that especially families with suboptimal child glycemic control showed more maternal distress and worse child well-being (according to parents). CONCLUSIONS: Families confronted with pediatric T1D differ from families without chronic illness: childhood T1D impacts parental perceptions of child well-being and differentially affects mothers' and fathers' distress levels and behaviors.

A Network Analysis of Potential Antecedents and Consequences of Pain-Related Activity Avoidance and Activity Engagement 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.

A Dyadic Perspective on Coping and its Effects on Relationship Quality and Psychological Distress in Couples Living with Chronic Pain: A Longitudinal Study.

OBJECTIVE: Dyadic coping is a process of coping within couples that is intended not only to support the patient with chronic pain but also to maintain equilibrium in the relationship. This study aims to investigate the effect of patient-perceived and spouse-reported dyadic coping on both the patient and their partner's relationship quality and anxiety, stress, and depression over time. METHODS: One hundred thirty-nine couples, with one partner experiencing chronic pain, participated in this study. Spanning three measurements over six months, couples reported on their anxiety, stress, depression, relationship quality, and dyadic coping. RESULTS: Patient-perceived supportive dyadic coping was positively associated with both partners' relationship quality but was negatively associated with spouses' stress over time. Patient-perceived negative dyadic coping was negatively associated with both partners' relationship quality and positively associated with patients' depression and spouses' depression and stress over time. Spouse-reported supportive dyadic coping showed a positive association with their own relationship quality and a negative association with spouses' depression at baseline and patients' depression at three-month follow-up. Spouse-reported negative dyadic coping was negatively associated with their relationship quality at baseline and positively associated with their partner's anxiety and stress at six-month and three-month follow-up, respectively. Similar inference was observed from the findings of growth curve model. CONCLUSIONS: As compared with spouse report, patient perception of dyadic coping is a better predictor of both partners' relationship quality and psychological outcomes over time. Both partners may benefit from early psychosocial intervention to improve their dyadic coping, relationship quality, and psychological outcomes.

Parental stress, anxiety and trait mindfulness: associations with parent-child mealtime interactions in children with type 1 diabetes.

Introduction This study examined how maternal and paternal stress, anxiety, and trait mindfulness, and child glycemic control are related to real-life parent-child interactions in families confronted with type 1 diabetes (T1D). Methods Parents reported on trait mindfulness, illness-related parenting stress, general stress, and state anxiety. Parent-child mealtime interactions were videotaped and scored in 33 families (31 mothers and 20 fathers) of children with T1D (5-12y., mean HbA1c = 7.22%). Results Parental stress and anxiety were related to more maladaptive and less adaptive parent-child interactions. For mothers, mindfulness was related to less observed discomfort of the child during injection. For fathers, more emotional involvement was related to better child glycemic control. Discussion Results indicate that parental stress and anxiety may be risk factors for maladaptive parent-child interactions.

Mindfulness, Worries, and Parenting in Parents of Children With Type 1 Diabetes.

OBJECTIVE: Parents of children with type 1 diabetes (T1D) often experience distress and worries, which may negatively impact their parenting behaviors. The current study investigates parental mindfulness (i.e., an enhanced attention to and awareness of current experiences or present reality) as a resilience mechanism. Using a daily diary approach, the predictive role of parental mindfulness for daily diabetes-related worries was examined, its impact upon protective parenting behaviors, and its buffering role in the relationship between daily worries and protective parenting behaviors. METHODS: Participants were 56 parents of 40 children with T1D (2-12 years). Trait mindfulness was assessed with the Mindful Attention Awareness Scale. Subsequently, parents completed a diary for 14 consecutive days, assessing parental worries about hypo- and hyperglycemia and general and diabetes-specific parental protective behavior. RESULTS: Multilevel analyses showed that parental diabetes-related worries fluctuated substantially across days and positively predicted daily protective behavior. Higher levels of parental mindfulness predicted less daily worries about hypoglycemia and lower engagement in general protective behavior and hypoglycemia avoidance behavior. In addition, the relationship between worries about hyperglycemia and general protective behavior was moderated by parental mindfulness. CONCLUSIONS: The present findings highlight the importance of daily parental worries in explaining parental protective behaviors on a daily basis. Mindfulness emerged as a promising resilience factor in parents of children with T1D, resulting in less daily worries and protective parenting. These results have important clinical implications and point to the promising role of mindfulness interventions in this context.

Helping Your Partner with Chronic Pain: The Importance of Helping Motivation, Received Social Support, and Its Timeliness.

Objective: Like all intentional acts, social support provision varies with respect to its underlying motives. Greater autonomous or volitional motives (e.g., enjoyment, full commitment) to help individuals with chronic pain (ICPs) are associated with greater well-being benefits for the latter, as indexed by improved satisfaction of their psychological needs for autonomy, competence, and relatedness. The present study investigates the processes explaining why partners' autonomous or volitional helping motivation yields these benefits. Methods: A total of 134 couples, where at least one partner had chronic pain, completed a 14-day diary. Partners reported on their daily helping motives, whereas ICPs reported on their daily received support, timing of help, need-based experiences, and pain. Results: On days when partners provided help for volitional motives, ICPs indicated receiving more help, which partially accounted for the effect of autonomous helping motivation on ICP need-based experiences. Timing of help moderated the effects of daily received support on ICP need-based experiences. Conclusions: Findings highlight the importance of ICPs of receiving support in general and the role of timing in particular, which especially matters when there is little support being received.

Classism in Pain Care: The Role of Patient Socioeconomic Status on Nurses' Pain Assessment and Management Practices.

OBJECTIVE: Research on social disparities in pain care has been mainly focused on the role of race/racism and sex/sexism. Classism in pain assessment and management practices has been much less investigated. We aimed to test the effect of patient socioeconomic status (SES; a proxy of social class) on nurses' pain assessment and management practices and whether patient SES modulated the effects of patient distress and evidence of pathology on such practices. DESIGN: Two experimental studies with a two (patient SES: low/high) by two (patient distress or evidence of pathology: absent/present) between-subject design. SUBJECTS: Female nurses participated in two experimental studies (N = 150/N = 158). METHODS: Nurses were presented with a vignette/picture depicting the clinical case of a female with chronic low back pain, followed by a video of the patient performing a pain-inducing movement. Afterwards, nurses reported their pain assessment and management practices. RESULTS: The low-SES patient's pain was assessed as less intense, more attributed to psychological factors, and considered less credible (in the presence of distress cues) than the higher-SES patient's pain. Higher SES buffered the detrimental impact of the presence of distress cues on pain assessment. No effects were found on management practices. CONCLUSIONS: Our findings point to the potential buffering role of SES against the detrimental effect of certain clinical cues on pain assessments. This study contributes to highlighting the need for further investigation of the role of SES/social class on pain care and its underlying meanings and processes.

Resilience Factors in Children with Juvenile Idiopathic Arthritis and Their Parents: The Role of Child and Parent Psychological Flexibility.

OBJECTIVE: Chronic pain is central to juvenile idiopathic arthritis (JIA) and is predictive of impaired functioning. Whereas most work has focused on identifying psychosocial risk factors for maladaptive outcomes, we explored the idea that child and parental psychological flexibility (PF) represent resilience factors for adaptive functioning of the child. We also explored differences between general vs pain-specific PF in contributing to child outcomes. METHODS: Children with JIA (age eight to 18 years) and (one of) their parents were recruited at the Department of Pediatric Rheumatology at the Ghent University Hospital in Belgium. They completed questionnaires assessing child and parent general and pain-specific PF and child psychosocial and emotional functioning and disability. RESULTS: The final sample consisted of 59 children and 48 parents. Multiple regression analyses revealed that child PF contributed to better psychosocial functioning and less negative affect. Child pain acceptance contributed to better psychosocial functioning, lower levels of disability, and lower negative affect, and also buffered the negative influence of pain intensity on disability. Bootstrap mediation analyses demonstrated that parental (general) PF indirectly contributed to child psychosocial functioning and affect via the child's (general) PF. Parent pain-specific PF was indirectly linked to child psychosocial functioning, disability, and negative affect via child pain acceptance. CONCLUSIONS: 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.

Parents' Perspectives of Changes Within the Family Functioning After a Pediatric Cancer Diagnosis: A Multi Family Member Interview Analysis.

Pediatric cancer is a life-threatening disease that challenges the life of the diagnosed child, the parents, and possible siblings. Moreover, it also places considerable demands on family life. The aim of this study was to explore changes in the family functioning after a pediatric cancer diagnosis. Ten couples who had a child with leukemia or non-Hodgkin lymphoma were interviewed individually about their experiences. Interviews were semistructured, and the data were analyzed using Multi Family Member Interview Analysis. Three themes emerged from the data: (a) Family Cohesion: Strengthened Versus Fragmented; (b) Educational Norms and Values: Overindulgence Versus Being Stricter, and (c) Normality: Loss Versus Preservation. The conflicting dynamics present in these emerging themes exemplify the complexity of this process of family adaptation. This study illustrates the need to take into account the family level, as well as the conflicting feelings parents may experience after a pediatric cancer diagnosis.

Maternal distress in the context of their child's type 1 diabetes: exploring the role of adaptive maternal emotion regulation on child outcomes.

Parents of children with Type 1 diabetes (T1D) experience high levels of distress, which may negatively impact child functioning. However, little is known about mechanisms that may buffer the adverse impact of parental distress. The current study explored the possible buffering role of maternal adaptive cognitive emotion regulation (CER) for the relationship between maternal distress and child psychological functioning. Forty-three children with T1D (8-15 years) completed measures assessing trait anxiety and depressive symptoms. Their mothers reported on general distress, illness-related parenting stress, and adaptive CER. Maternal illness-related parenting stress (but not general distress) was significantly associated with child psychological functioning. No buffering role for maternal adaptive CER was observed. As the current study is rather preliminary, future research using other methods to examine maternal adaptive CER, and examining other parental variables that may buffer against the negative impact of parental distress is warranted.

Illness Identity in Adults with a Chronic Illness.

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

Couple functioning after pediatric cancer diagnosis: a systematic review.

OBJECTIVES: A systematic review was conducted to (1) investigate couple functioning after a pediatric cancer diagnosis and (2) examine theoretical and methodological tendencies and issues in this literature. METHODS: Searches of Web of Science, PubMed, Cochrane, PsycINFO, and Embase resulted in inclusion of 32 qualitative, quantitative, or mixed-method papers. Findings of these papers were extracted for summary. RESULTS: Most couples adapt well to the crisis of a pediatric cancer diagnosis in domains such as emotional closeness, support, marital satisfaction, and general marital adjustment. However, most experience difficulties in the domain of sexual intimacy, and reports on conflict are mixed across qualitative and quantitative studies. CONCLUSIONS: This review illustrates the need for future research with a greater focus on the impact of a pediatric cancer diagnosis on the couple's functioning, conducted with the use of appropriate theoretical frameworks and based on both partners' reports. Improvements in research are needed to best inform couple-based interventions.

Systematic Review: Associations Between Family Functioning and Child Adjustment After Pediatric Cancer Diagnosis: A Meta-Analysis.

Objectives: A systematic review and meta-analysis was conducted to investigate associations between family functioning and child adjustment (patient/siblings) after pediatric cancer diagnosis. Methods: Database searches were performed using Web of Science, Pubmed, Cochrane, PsycInfo, and Embase. After screening 5,563 articles, 35 were identified regarding this topic; 30 contributed data for meta-analyses. Pearson's r correlations were the effect of interest. Omnibus and family functioning domain-specific random-effects meta-analyses were conducted. Data are depicted in forest plots. Results: A statistically significant association was found between family functioning and child adjustment (patient/siblings) after cancer diagnosis (r = 0.19; 95% CI: 0.13­0.24). Greater family cohesion, expressiveness, and support and less family conflict were each associated with better child adjustment outcomes. Conclusions Family functioning is associated with patient and sibling adjustment after pediatric cancer diagnosis. Limitations in the existing literature preclude strong conclusions about the size of these effects and potential moderators.

Personal Distress and Sympathy Differentially Influence Health Care Professional and Parents' Estimation of Child Procedure-Related Pain.

Objective: Caregivers' pain estimations may have important implications for pediatric pain management decisions. Affective responses elicited by facing the child in pain are considered key in understanding caregivers' estimations of pediatric pain experiences. Theory suggests differential influences of sympathy versus personal distress on pain estimations; yet empirical evidence on the impact of caregivers' feelings of sympathy versus distress upon estimations of pediatric pain experiences is lacking. The current study explored the role of caregiver distress versus sympathy in understanding caregivers' pain estimates of the child's pain experience. Design, Setting, Subjects and Methods: Using a prospective design in 31 children undergoing consecutive lumbar punctures and/or bone marrow aspirations at Ghent University Hospital, caregivers' (i.e., parents, physicians, nurses, and child life specialists) distress and sympathy were assessed before each procedure; estimates of child pain were obtained immediately following each procedure. Results: Results indicated that the child's level of pain behavior in anticipation of the procedure had a strong influence on all caregivers' pain estimations. Beyond the impact of child pain behavior, personal distress explained parental and physician's estimates of child pain, but not pain estimates of nurses and child life specialists. Specifically, higher level of parental and physician's distress was related to higher child pain estimates. Caregiver sympathy was not associated with pain estimations. Conclusions: The current findings highlight the important role of caregivers' felt personal distress when faced with child pain, rather than sympathy, in influencing their pain estimates. Potential implications for pain management are discussed.

Street characteristics preferred for transportation walking among older adults: a choice-based conjoint analysis with manipulated photographs.

BACKGROUND: Knowledge about the relationships between micro-scale environmental factors and older adults' walking for transport is limited and inconsistent. This is probably due to methodological limitations, such as absence of an accurate neighborhood definition, lack of environmental heterogeneity, environmental co-variation, and recall bias. Furthermore, most previous studies are observational in nature. We aimed to address these limitations by investigating the effects of manipulating photographs on micro-scale environmental factors on the appeal of a street for older adults' transportation walking. Secondly, we used latent class analysis to examine whether subgroups could be identified that have different environmental preferences for transportation walking. Thirdly, we investigated whether these subgroups differed in socio-demographic, functional and psychosocial characteristics, current level of walking and environmental perceptions of their own street. METHODS: Data were collected among 1131 Flemish older adults through an online (n = 940) or an interview version of the questionnaire (n = 191). This questionnaire included a choice-based conjoint exercise with manipulated photographs of a street. These manipulated photographs originated from one panoramic photograph of an existing street that was manipulated on nine environmental attributes. Participants chose which of two presented streets they would prefer to walk for transport. RESULTS: In the total sample, sidewalk evenness had by far the greatest appeal for transportation walking. The other environmental attributes were less important. Four subgroups that differed in their environmental preferences for transportation walking were identified. In the two largest subgroups (representing 86% of the sample) sidewalk evenness was the most important environmental attribute. In the two smaller subgroups (each comprising 7% of the sample), traffic volume and speed limit were the most important environmental attributes for one, and the presence of vegetation and a bench were the most important environmental attributes for the other. This latter subgroup included a higher percentage of service flat residents than the other subgroups. CONCLUSIONS: Our results suggest that the provision of even sidewalks should be considered a priority when developing environmental interventions aiming to stimulate older adults' transportation walking. Natural experiments are needed to confirm whether our findings can be translated to real environments and actual transportation walking behavior.
