RESUMO

OBJECTIVE: Complications during pregnancy can negatively impact the physical and psychological wellbeing of mothers. This systematic review aimed to synthesise evidence which has examined the impact of high-risk conditions developed during pregnancy on women's coping, wellbeing, and symptoms of psychopathology. DATA SOURCES: Medline (Ovid), PsycINFO (ProQuest), Scopus, Web of science, AMED (Ebsco), CINAHL (Ebsco) and ProQuest databases were searched in May 2021 with no restrictions on publication date. STUDY SELECTION: English-language literature was reviewed to identify 31 articles. DATA EXTRACTION: Fifteen articles examined Gestational Diabetes Mellitus (GDM: 48%), nine examined multiple high-risk pregnancy conditions (29%), four examined Hypertensive disorders of pregnancy, Preeclampsia (PE: 13%), two did not specify the condition examined (7%), and one examined Pregnancy-Related Acute Kidney Injury (PR-AKI: 3%). The most common study design was quantitative, non-randomised, and survey-based. DATA SYNTHESIS: Twenty-seven articles (87%) reported a high-risk pregnancy resulted in decreased wellbeing and ability to cope, and increased symptoms of psychopathology. The remaining four articles (13%) reported no difference in wellbeing or psychopathology outcomes for women experiencing high-risk compared to healthy pregnancies. Moreover, hypertensive disorders and GDM were associated with ineffective submissive or avoidant coping, reduced wellbeing, and quality-of-life, and exacerbated symptoms of anxiety and depression. CONCLUSION: High-risk pregnancy negatively impacts coping, wellbeing, and psychopathology, and preventive and supportive interventions to mitigate this should focus on empowering women to feel optimistic and in control of their pregnancy. A holistic and culturally sensitive approach is recommended, where pregnant women (and their partners or support people) are involved in healthcare decisions, thus promoting wellbeing, coping, satisfaction, and improved treatment outcome.

RESUMO

The Self-Regulation for Learning Online (SRL-O) questionnaire was developed to encompass the breadth of motivational beliefs and learning strategies that are often used in online and/or blended learning contexts. No current measure meets all these needs. This study used two non-duplicate samples to provide evidence of the psychometric properties of SRL-O using exploratory factor analyses (sample 1, n = 313), and confirmatory factor analyses, convergent and content validity and reliability (sample 2, n = 321). The SRL-O has a 10-factor structure, made up of (1) online self-efficacy, (2) online intrinsic motivation, (3) online extrinsic motivation, (4) online negative achievement emotion, (5) planning and time management, (6) metacognition, (7) study environment, (8) online effort regulation, (9) online social support, and (10) online task strategies. The SRL-O was also found to have two superordinate factors (motivational beliefs and learning strategies). The SRL-O was demonstrated to be a psychometrically sound measure of online SRL for learners studying in online and blended learning contexts. There is no other online self-regulated learning questionnaire that currently covers such a wide range of motivational beliefs and learning strategies.

RESUMO

Help-seeking is an essential self-regulatory and metacognitive skill. In the online learning environment, much of the learning is self-directed and there are generally less opportunities to receive help in real time. The uses of email and discussion boards are the most common method of seeking help in these environments. The current study explored students' perceptions of the use of live chat technology for online academic help-seeking within higher education, with a focus on comparing online and blended learners' perspectives. Participants were 246 students who were studying psychology online (n = 91) or in blended learning (n = 155) environments. The live chat technology was well received by both groups, especially for its ability to provide instant, real-time, and convenient help. Live chat was particularly well received by online learners, who were more satisfied, felt more cared about by the teaching team, and would be more likely to recommend it to others than blended learners. Further, online learners reported that live chat gave them better access to staff, and felt that this feature was a good approximation for more traditional face-to-face conversations. As an online, synchronous, private help-seeking tool between student and teacher, these findings provide a strong endorsement for the use of live chat in higher education, particularly for online learners.

RESUMO

BACKGROUND: Technological advancements make it possible to deliver depression interventions via smartphone applications ("Apps"), including those that deliver content "just-in-time" (e.g., in response to acute negative mood states). This study examined whether an app-based just-in-time intervention (ImproveYourMood+) decreased depressive symptoms, and whether the following features were related to symptom improvement: micro-intervention content, mood monitoring, and just-in-time prompts to use content. METHODS: Participants (n = 235) from the general population who self-identified as wanting to improve their negative mood were randomised to a waitlist control group (n = 55) or one of three intervention groups: MoodTracker (monitoring-only, n = 58), ImproveYourMood (monitoring and content; n = 62), or ImproveYourMood+ (monitoring, content, and prompts; n = 60). The active intervention phase was 3 weeks. Depressive and anxiety symptoms, and negative automatic thoughts were assessed at baseline, immediately post-intervention, and one month following post-intervention. RESULTS: Linear mixed modelling revealed greater declines over time in depressive and anxiety symptoms and negative automatic thoughts for the ImproveYourMood group (standardized mean differences [SMDs] ranged from .32 to .40) and improves for the ImproveYourMood+ group for negative automatic thoughts (SMDs ≥ .37) compared to the waitlist control group. No between-group differences were observed between the MoodTracker and control groups (SMDs = .04-.23). User experience appeared to be superior in more comprehensive/multi-modal versions. LIMITATIONS: The study employed a naturalistic design, whereby participants self-selected to utilise the program, did not complete eligibility assessments, and did not receive compensation. The study therefore attained considerable drop-out rate (~50% by the follow-up timepoints), potentially reflecting the usage patterns of real-world mental health apps. CONCLUSIONS: The findings suggest that micro-interventions can be an effective way to reduce depressive symptoms both in the moment and 1-2 months later. Integration of micro-interventions with full treatment programs is a viable next step in micro-intervention research.

RESUMO

The objective of the present study was to compare body dissatisfaction of pregnant (n = 1245 overall; n = 320 trimester 1, n = 497 trimester 2, n = 428 trimester 3) and non-pregnant (n = 547) women in terms of: (a) global dissatisfaction, (b) dissatisfaction with specific body parts/features, and (c) strength of inter-relation among these areas of dissatisfaction. While ANOVAs revealed small group differences in overall body dissatisfaction ratings for appearance and function, more sizable differences were observed at the item level. Network analysis showed that the dissatisfaction items clustered together in similar ways across groups, but that the relative importance of these items for the networks differed by group. In particular, dissatisfaction with chest was much less connected to other areas of dissatisfaction for pregnant women, whilst dissatisfaction with shape and/or weight were more strongly connected to other items for this group. Body function items were less important in the network for non-pregnant women. Findings support earlier qualitative findings suggesting that pregnant women are concerned with both appearance and functioning of their bodies. More broadly, information gleaned at the item level highlights the value in exploring areas of dissatisfaction that may increase understanding of global dissatisfaction ratings.

RESUMO

Accumulating lab-based studies have identified attentional biases in processing of negative appearance-related information among individuals with elevated trait body shape and weight dissatisfaction (BD). How these biases translate into experiences of BD in daily life remains unclear and, hence, was the focus of the present study. Thirty-eight women aged between 18-40 years completed a baseline survey and modified dot-probe task with both fat and thin appearance-related stimuli in a laboratory setting. Participants also downloaded a smartphone app that prompted them 10 times per day for 7 days to rate current body dissatisfaction. Results revealed that heightened BD in daily life tended to be transitory, and followed by a substantially lower rating of BD by the next survey (∼1-2 h later). For individuals with elevated trait BD and facilitated attention towards thin body images, this reduction in state BD was more gradual. Surprisingly, delayed disengagement towards thin body images was associated with greater reduction in state BD. Consistent with the hypothesis, moderating effects were not observed when initial state BD level was low. Susceptibility for immediate, short-term attentional biases towards appearance-related information may be a vulnerability factor for the prolonged persistence of negative body image experiences in daily life.

RESUMO

Although appearance comparisons, self-monitoring, and appearance-related comments have been linked to body dissatisfaction in prior studies, the combined and unique influences of these variables on state body dissatisfaction in daily life has yet to be explored. The present study addressed this gap, and also evaluated whether these state-based effects were stronger for individuals with trait-level body image disturbances (internalization and body dissatisfaction). Eighty-four women completed baseline measures of trait internalization and body dissatisfaction, and then reported momentary experiences of body dissatisfaction, appearance self-monitoring, appearance-related comments, and appearance-based comparisons at up to 10 random times daily for seven days. Multilevel analyses confirmed that both appearance comparisons and commentary (both negative and positive) were predictive of changes in state body dissatisfaction when modelled individually as well as in a combined (full) model. Appearance self-monitoring was not a significant predictor, either individually or in the full model. These within-person relationships were not moderated by individual differences in trait body dissatisfaction and internalization of appearance standards. Accordingly, experiences of body dissatisfaction in daily life may be a common reaction to negative appearance comments and unflattering comparisons, yet positive comments and/or efforts to avoid appearance-based comparisons may have a positive effect on one's body image.

RESUMO

BACKGROUND: A range of psychological constructs, including perceived pain, self-efficacy, and pain avoidance, have been proposed to account for the comorbidity of chronic pain and affective disorder symptoms. Despite the likely inter-relation among these constructs, few studies have explored these predictors simultaneously. As such, the relative contributions of these psychological influences remain an open question. PURPOSE: The present study uses a novel, network model approach to help to identify the key psychological contributors to the pain-affective disorder link. METHOD: A cross-sectional design was implemented. The sample comprised 169 individuals with chronic pain (Mage 49.82; range 22-80 years; 58% female) admitted to a metropolitan chronic pain clinic in Victoria, Australia. Participants completed self-report measures of anxiety, depressive, and pain symptoms, pain self-efficacy, fear avoidance beliefs, perceived control, and pain-related disability. RESULTS: Network analysis identified self-efficacy, fear avoidance, and perceived disability as key constructs in the relationship between pain and affective disorder symptoms, albeit in different ways. While self-efficacy appeared to have direct links to other constructs in the network model, fear avoidance and perceived disability seemed to function more as mediators, linking other constructs in the model. Perceived control and anxiety were found to be less influential in the model. CONCLUSIONS: Present findings identify self-efficacy, fear avoidance, and perceived disability as plausible candidate variables to target to disrupt the link between pain experience and affective disorder symptoms. However, further testing with longitudinal designs is needed to confirm this.

RESUMO

BACKGROUND: The relationship between self-report trait level restriction and daily engagement in restriction behaviors is not well understood, and as a result the usefulness of such trait level measures is unclear. The present study aimed both to examine the validity of self-reported trait dietary restraint behaviors, and to examine the respective relationships among self-reported trait dietary restraint intentions and behaviors and both restrained and disinhibited eating at the daily level. METHODS: A sample of 109 women (Mage = 24.72, SD = 4.15) completed a self-report trait level measure of dietary restraint before providing EMA data on their daily engagement in dietary restraint and disinhibited eating behaviors, as well as mood, over a period of 7 days. Multilevel hurdle models were used to test the relationship between trait levels of dietary restraint, and daily level reports of restraint and disinhibited eating behaviors. RESULTS: Trait restraint behavior was a consistent predictor of daily presence and frequency of restraint behaviors. In contrast, trait restraint intentions was not a predictor of daily restraint behaviors, however it did predict daily frequency of overeating. In addition, daily negative affect emerged as a predictor of comfort eating, but was not predictive of restraint behaviors. CONCLUSIONS: Findings confirm the usefulness of assessments of self-reported trait dietary restraint behaviors as a method of capturing dieting behaviors. In contrast, trait level dietary restraint intentions was a poor predictor of eating outcomes and more research on the way that restraint intentions affect eating behaviors is warranted.

RESUMO

BACKGROUND AND AIMS: Clinicians treating paediatric chronic pain conditions understand that persistent pain, functional ability, and symptoms of depression often co-exist, yet these relationships have only been described to a limited extent by research. This paper more closely examines the relationship between symptoms of depression and subtypes of functional disability. METHODS: Participants included a clinical sample of children and adolescents (N=239) referred to a paediatric multidisciplinary pain clinic for treatment of persistent or recurrent (chronic) pain in Australia. The majority of participants were female, (76.6%), and were aged 7-17 years (mean age at the time of presentation was 13.8 years). Data from standardized instruments and interview data were collected from a clinical file audit. The Pediatric Outcomes Data Collection Instrument (PODCI) was used as a measure of functional difficulties performing activities of daily living, and the Children's Depression Inventory (CDI) was used to measure depressive symptoms. RESULTS: High rates of depression and functional disability were observed, but were not associated with one another beyond relatively weak associations. Contrary to prior studies using different measures of physical functioning, depression symptoms were not associated with PODCI functional disability beyond a minor association with anhedonia symptoms (primarily driven by the pain/comfort subscale of the PODCI). CONCLUSIONS AND IMPLICATIONS: We argue that prior research has measured physical functional limitations in paediatric pain sufferers in a way that is heavily influenced by psychosocial factors, in particular by the symptoms of clinical depression. In contrast, using a measure of physical functioning (PODCI) less influenced by psychosocial factors suggests that the relationship between physical functioning during activities of daily living (e.g., use of upper limbs, basic gross and fine motor skills, basic mobility) and depression is weaker, despite both being heightened in this sample. Unlike other functional disability measures, the Pediatric Outcomes Data Collection Instrument (PODCI) may allow researchers to assess functional limitations somewhat independently of depression symptoms. This conclusion requires replication in further studies, but if confirmed, then the PODCI could be advocated as a useful measure to obtain a more 'pure' measure of functional difficulties due to pain, relatively independent of depression.

RESUMO

This study developed and validated a quantitative measure of body image specifically designed for pregnancy-the Body Image in Pregnancy Scale (BIPS). Scale development was guided by qualitative data from a series of studies exploring the meaning of women's body image experiences during pregnancy, and previously established body image measures. Exploratory factor analysis for a sample of pregnant women (n = 251) indicated good fit for a 36-item scale with seven factors: preoccupation with physical appearance, dissatisfaction with physical strength, dissatisfaction with facial features, sexual attractiveness, prioritizing physical appearance over body functioning, appearance-related behavioral avoidance, and dissatisfaction with body parts. BIPS subscale scores demonstrated good internal reliability, test-retest reliability, and both incremental and convergent validity with measures of body image, self-esteem, and depressive symptomatology. Although the pregnancy-focused wording of BIPS items prevents its use for comparisons with nonpregnant populations, further testing of changes in body image throughout pregnancy is an identified area for further research with this measure.

RESUMO

OBJECTIVES: This study utilised the preload paradigm to evaluate whether trait-like dieting attitudes and behaviours (dietary restraint and flexibility in dieting rules) and context-specific factors (negative mood and hunger) predict food consumption among male and female participants. METHODS: Following a high calorie preload, 79 participants aged 18-40 completed a deceptive taste test in which they were encouraged to eat as much of the taste test foods as desired, and this ad libitum intake was measured. RESULTS: Although each predictor (except negative mood) predicted consumption when tested individually, regression analyses revealed that dieting flexibility and current hunger were the strongest unique predictors of intake. Mood failed to directly predict food consumption, nor did it moderate the relationship between restraint and food intake. CONCLUSION: Collectively, findings suggest that emphasis on dietary restraint in preload studies may be misplaced, as other proximal and stable factors may better predict food consumption.

RESUMO

OBJECTIVES: To understand how pain-related cognitions predict and influence treatment retention and adherence during and after a multidisciplinary rehabilitation program. METHODS: Electronic databases including Medline, CINAHL, PsycINFO, Academic Search Complete, and Scopus were used to search 3 combinations of key words: chronic pain, beliefs, and treatment adherence. RESULTS: The search strategy yielded 591 results, with an additional 12 studies identified through reference screening. Eighty-one full-text papers were assessed for eligibility and 10 papers met the inclusion and exclusion criteria for this review. The pain-related beliefs that have been measured in relation to treatment adherence include: pain-specific self-efficacy, perceived disability, catastrophizing, control beliefs, fear-avoidance beliefs, perceived benefits and barriers, and other less commonly measured beliefs. The most common pain-related belief investigated in relation to treatment adherence was pain-related self-efficacy. Findings for the pain-related beliefs investigated among the studies were mixed. Collectively, all of the aforementioned pain-related beliefs, excluding control beliefs, were found to influence treatment adherence behaviors. DISCUSSION: The findings suggest that treatment adherence is determined by a combination of pain-related beliefs either supporting or inhibiting chronic pain patients' ability to adhere to treatment recommendations over time. In the studies reviewed, self-efficacy appears to be the most commonly researched predictor of treatment adherence, its effects also influencing other pain-related beliefs. More refined and standardized methodologies, consistent descriptions of pain-related beliefs, and methods of measurement will improve our understanding of adherence behaviors.

RESUMO

BACKGROUND: Pregnancy provides an interesting challenge to body image theories in that the natural physiological changes push women further from the socioculturally prescribed thin ideal which these theories hinge upon. The impact that these significant physiological changes have on the woman's body image during pregnancy may depend on the extent to which they retain or revise the ideal. However, little is known about body image experiences during pregnancy. AIM: To provide a comprehensive exploration of the body image experiences of pregnant women. METHODS: Individual structured interviews were conducted with 19 currently pregnant women. Transcriptions were analysed using a thematic content analysis approach. FINDINGS: Themes extracted from the qualitative data included: (1) women's body image experiences during pregnancy were complex and changing, and shaped by the salience of specific body parts, the women's expectations for future changes to their body within the perinatal period, the functionality of the body, and their experience of maternity clothing, (2) women were able to negotiate the changes to their bodies as they recognised the functionality of the pregnant body, (3) women were surprised by the public nature of the pregnant body, (4) partner support and positive feedback about the pregnant body was highly valued, and (5) the importance of open communication around weight and body image in antenatal healthcare. DISCUSSION: Our findings highlight the need for the adaptation and expansion of existing body image theories to be used as a framework for women's experiences of pregnancy.

RESUMO

Literature reporting body image disturbances across the perinatal period has produced inconsistent findings, owing to the complexity of body image experiences during pregnancy and the first year postpartum. Existing qualitative data might provide potential avenues to advance understanding of pregnancy-related body image experiences and guide future quantitative research. The present systematic review synthesised the findings of 10 qualitative studies exploring the body image experiences of women through the perinatal period, albeit the majority focused only on pregnancy. Themes emerging included malleability of body image ideals across pregnancy (including the shift from aesthetic to functional concerns about one's appearance), the salience of stomach and breasts for self-rated body satisfaction, and perceived pressure to limit weight gain across pregnancy in order to return quickly to pre-pregnancy figure following birth. These qualitative findings suggest greater complexity of body image experiences during perinatal period than can be captured by typically used self-report measures.

RESUMO

PURPOSE: The present study tests several competing, explanatory models-dual pathways, escape from awareness, and objectification theory-for the established link between body dissatisfaction and binge eating. METHODS: 408 women aged between 18 and 40 years completed a survey designed to assess contributions of proposed mediators (dietary restraint and negative affect from the dual pathway model, self-distraction from the escape from awareness model, and interoceptive deficits from objectification theory) for the body dissatisfaction-binge eating relationship. RESULTS: Although mediation analyses supported the dual pathway model and objectification theory when tested separately, the dual pathway model most strongly predicted the body dissatisfaction-binge eating relationship. Both model-implied mediators (dietary restraint and negative affect) made significant unique contributions, accounting for roughly one-quarter of the shared variance between body dissatisfaction and binge eating when tested separately from other mediators. Improvements in variance explained were negligible once other proposed mediators were included in a test of models combined. CONCLUSIONS: Collectively, these findings suggest the superiority of the dual pathway model over objectification theory and the escape model, but the remaining unaccounted for covariance suggests need to consider alternative mechanisms that may also account for the relationship between body dissatisfaction and binge eating.

RESUMO

OBJECTIVE: to examine the effect of psychosocial factors on exclusive breastfeeding duration to six months postpartum DESIGN: longitudinal, prospective questionnaire based study. SETTING: participants were recruited from a publically funded antenatal clinic located in the western metropolitan region of Melbourne, Victoria, Australia and asked to complete questionnaires at three time points; 32 weeks pregnancy, two months postpartum and six months postpartum. PARTICIPANTS: the participants were 125 pregnant women aged 22-44 years. MEASUREMENTS AND FINDINGS: psychosocial variables such as breastfeeding self-efficacy, body attitude, psychological adjustment, attitude towards pregnancy, intention, confidence and motivation to exclusively breastfeed and importance of exclusive breastfeeding were assessed using a range of psychometrically validated tools. Exclusive breastfeeding behaviour up to six months postpartum was also measured. At 32 weeks gestation a woman's confidence to achieve exclusive breastfeeding was a direct predictor of exclusive breastfeeding duration to six months postpartum. At two months postpartum, psychological adjustment and breastfeeding self-efficacy were predictive of exclusive breastfeeding duration. Finally, at six months postpartum, psychological adjustment, breastfeeding self-efficacy, confidence to maintain and feeling fat were directly predictive of exclusive breastfeeding duration. KEY CONCLUSIONS: psychosocial factors are significantly predictive of exclusive breastfeeding duration. Self-efficacy, psychological adjustment, body image, motivation and confidence are all important psychosocial factors implicated in a woman's ability to maintain exclusive breastfeeding over time. IMPLICATIONS FOR PRACTICE: Individualised antenatal breastfeeding education and support may be strengthened by strategies that build a woman's confidence to exclusive breastfeeding. Implementing psychosocial supports and methods providing positive feedback that increase a woman's self-efficacy to exclusively breastfeed to six months are also important two months postpartum.

RESUMO

BACKGROUND: Although a wealth of studies have tested the link between negative mood states and likelihood of a subsequent binge eating episode, the assumption that this relationship follows a typical linear dose-response pattern (i.e., that risk of a binge episode increases in proportion to level of negative mood) has not been challenged. The present study demonstrates the applicability of an alternative, non-linear conceptualization of this relationship, in which the strength of association between negative mood and probability of a binge episode increases above a threshold value for the mood variable relative to the slope below this threshold value (threshold dose response model). METHODS: A sample of 93 women aged 18 to 40 completed an online survey at random intervals seven times per day for a period of one week. Participants self-reported their current mood state and whether they had recently engaged in an eating episode symptomatic of a binge. RESULTS: As hypothesized, the threshold approach was a better predictor than the linear dose-response modeling of likelihood of a binge episode. The superiority of the threshold approach was found even at low levels of negative mood (3 out of 10, with higher scores reflecting more negative mood). Additionally, severity of negative mood beyond this threshold value appears to be useful for predicting time to onset of a binge episode. CONCLUSIONS: Present findings suggest that simple dose-response formulations for the association between negative mood and onset of binge episodes miss vital aspects of this relationship. Most notably, the impact of mood on binge eating appears to depend on whether a threshold value of negative mood has been breached, and elevation in mood beyond this point may be useful for clinicians and researchers to identify time to onset.
