Sexting prevalence and correlates: a systematic literature review.

Bianca Klettke; David John Hallford; David Mellor

Despite considerable controversy and speculation regarding sexting behaviour and its associated risks, to date there has been no integration and analysis of empirical literature on this topic. To collect and synthesise findings of the prevalence of sexting, its correlates, and the context in which it occurs, a systematic search of databases was conducted. Thirty-one studies, reporting on sexting prevalence and a diverse range of related variables, met inclusion criteria. The estimated mean prevalence weighted by sample size was calculated, with trends indicating sexting is more prevalent amongst adults than adolescents, older age is predictive of sexting for adolescents but not adults, and more individuals report receiving sexts than sending them. The correlates of sexting behaviour were grouped in terms of demographic variables, sexual and sexual risk behaviours, attitudes towards sexting, perceived outcomes of sexting, motivations for sexting, mental health and well-being variables, and attachment dimensions. Findings are discussed in terms of the trends indicated by the data, which provided substantiation that sexting behaviour is associated with numerous behavioural, psychological, and social factors. Limitations of the current research literature and future directions are also presented.

Adaptive autobiographical memory in younger and older adults: The indirect association of integrative and instrumental reminiscence with depressive symptoms

David John Hallford; David Mellor; Robert A. Cummins

Despite the established effectiveness of reminiscence-based interventions for depression, little research exists into the pathways through which specific reminiscence functions are related to depressive symptoms. Drawing on theory of the mechanisms of change in cognitive-reminiscence therapy, the current study tests the hypothesised indirect associations of adaptive integrative and instrumental reminiscence functions with depressive symptoms and whether these relationships might differ among younger and older adults. Questionnaires were completed by a large community sample of the Australian population. Multiple mediation models were tested in two groups: younger adults (n = 730, M age = 52.24, SD=9.84) and older adults (n = 725, M age= 73.59, SD=6.29). Results were consistent across age groups, indicating that there was direct relationship between these reminiscence functions and depressive symptoms, but that integrative reminiscence is indirectly associated with depressive symptoms through meaning in life, self-esteem, and optimism, and that instrumental reminiscence is indirectly associated with depressive symptoms through primary control and self-efficacy. This study provides support for the relationships between constructs underlying the proposed mechanisms of change in cognitive-reminiscence therapy for the treatment of depression, and suggests these relationships are similar for younger and older adults.

Objectives: Behavioral and psychological symptoms of dementia (BPSD) cause significant stress and distress to both aged-care residents and staff. This study evaluated a training program to assist staff to manage BPSD in residential care. Method: A randomised controlled trial (RCT) was employed. The study was included in the Australian and New Zealand Clinical Trial Register residential care facilities. Staff (n = 204) and residents (n = 187) were from 16 residential care facilities. Facilities were recruited and randomly assigned to four staff training conditions: (1) training in the use of a BPSD-structured clinical protocol, plus external clinical support, (2) a workshop on BPSD, plus external clinical support, (3) training in the use of the structured clinical protocol alone, and (4) care as usual. Staff and resident outcome measures were obtained pre-intervention, three months and six months post-intervention. The primary outcome was changes in BPSD, measured using the Cohen-Mansfield Agitation Inventory (CMAI) as well as frequency and duration of challenging behaviors. Secondary outcomes were changes in staff adjustment. Results: There were improvements in challenging behaviors for both intervention conditions that included training in the BPSD instrument, but these were not maintained in the condition without clinical support. The training/support condition resulted in sustained improvements in both staff and resident variables, whereas the other conditions only led to improvement in some of the measured variables. Conclusion: These results demonstrate the effectiveness of the BPSD protocol in reducing BPSD and improving staff self-efficacy and stress.

The Association Between Anxiety and Falls: A Meta-Analysis

David John Hallford; Geoffrey C. Nicholson; Kerrie M. Sanders; Marita P. McCabe

Objectives Falls occur frequently among older adults and can lead to a range of adverse and debilitating outcomes. Although symptoms of clinical anxiety have been implicated as risk factors for falls, there is no current consensus on the empirical association between anxiety and falls. The current study aimed to address this gap in the literature by conducting a quantitative, meta-analytic review of findings from previous studies. Method A systematic literature search of bibliographic databases was conducted, yielding 18 studies that fit the criteria for inclusion in the meta-analysis. Results A random-effects model of all 18 studies showed a significant overall odds ratio of 1.53 (95% CI 1.28-1.83, p < .001), indicating that elevated levels of anxiety were associated with a 53% increased likelihood of falls. A high amount of variance among effect sizes was observed. Only age was identified as a moderator of this relationship in a subgroup of the samples. Conclusions Clinical anxiety is associated with falls, however, further research is required to elucidate the factors that might moderate or mediate this relationship, the casual pathways through which they are related, and the associations between different types of anxiety and falls.

Brief reminiscence activities improve state well-being and self-concept in young adults: a randomised controlled experiment

David John Hallford; David Mellor

ABSTRACT Reminiscence-based psychotherapies have been demonstrated to have robust effects on a range of therapeutic outcomes. However, little research has been conducted on the immediate effects of guided activities they are composed of, or how these might differ dependent on the type of reminiscence. The current study utilised a controlled experimental design, whereby 321 young adults (mean age = 25.5 years, SD = 3.0) were randomised to one of four conditions of online reminiscence activity: problem-solving (successful coping experiences), identity (self-defining events contributing to a meaningful and continuous personal identity), bitterness revival (negative or adverse events), or a control condition (any memory from their past). Participants recalled autobiographical memories congruent with the condition, and answered questions to facilitate reflection on the memories. The results indicated that problem-solving and identity reminiscence activities caused significant improvements in self-esteem, meaning in life, self-efficacy and affect, whereas no effects were found in the bitterness revival and control conditions. Problem-solving reminiscence also caused a small effect in increasing perceptions of a life narrative/s. Differences between the conditions did not appear to be explained by the positive-valence of memories. These results provide evidence for the specific effects of adaptive types of problem-solving and identity reminiscence in young adults.

Promoting fit bodies, healthy eating and physical activity among Indigenous Australian men: a study protocol

Lina A. Ricciardelli; David Mellor; Marita P. McCabe; Alexander J. Mussap; David John Hallford; Matthew Tyler

BackgroundOverall the physical health of Indigenous men is among the worst in Australia. Research has indicated that modifiable lifestyle factors, such as poor nutrition and physical inactivity, appear to contribute strongly to these poor health conditions. To effectively develop and implement strategies to improve the health of Australias Indigenous peoples, a greater understanding is needed of how Indigenous men perceive health, and how they view and care for their bodies. Further, a more systematic understanding of how sociocultural factors affect their health attitudes and behaviours is needed. This article presents the study protocol of a community-based investigation into the factors surrounding the health and body image of Indigenous Australian men.Methods and designThe study will be conducted in a collaborative manner with Indigenous Australian men using a participatory action research framework. Men will be recruited from three locations around Australia (metropolitan, regional, and rural) and interviewed to understand their experiences and perspectives on a number of issues related to health and health behaviour. The information that is collected will be analysed using modified grounded theory and thematic analysis. The results will then be used to develop and implement community events in each location to provide feedback on the findings to the community, promote health enhancing strategies, and determine future action and collaboration.DiscussionThis study will explore both risk and protective factors that affect the health of Indigenous Australian men. This knowledge will be disseminated to the wider Indigenous community and can be used to inform future health promotion strategies. The expected outcome of this study is therefore an increased understanding of health and health change in Indigenous Australian men, the development of strategies that promote healthy eating and positive patterns of physical activity and, in the longer term, more effective and culturally-appropriate interventions to improve health.

Cognitive-reminiscence therapy and usual care for depression in young adults: study protocol for a randomized controlled trial

David John Hallford; David Mellor

BackgroundDepression is a common affliction for young adults, and is associated with a range of adverse outcomes. Cognitive-reminiscence therapy is a brief, structured intervention that has been shown to be highly effective for reducing depressive symptoms, yet to date has not been evaluated in young adult populations. Given its basis in theory-guided reminiscence-based therapy, and incorporation of effective therapeutic techniques drawn from cognitive therapy and problem-solving frameworks, it is hypothesized to be effective in treating depression in this age group.Methods and designThis article presents the design of a randomized controlled trial implemented in a community-based youth mental health service to compare cognitive-reminiscence therapy with usual care for the treatment of depressive symptoms in young adults. Participants in the cognitive-reminiscence group will receive six sessions of weekly, individual psychotherapy, whilst participants in the usual-care group will receive support from the youth mental health service according to usual procedures. A between-within repeated-measures design will be used to evaluate changes in self-reported outcome measures of depressive symptoms, psychological wellbeing and anxiety across baseline, three weeks into the intervention, post-intervention, one month post-intervention and three months post-intervention. Interviews will also be conducted with participants from the cognitive-reminiscence group to collect information about their experience receiving the intervention, and the process underlying any changes that occur.DiscussionThis study will determine whether a therapeutic approach to depression that has been shown to be effective in older adult populations is also effective for young adults. The expected outcome of this study is the validation of a brief, evidence-based, manualized treatment for young adults with depressive symptoms.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12613000084785.

BACKGROUND Despite being a relatively prevalent and debilitating disorder, Generalized Anxiety Disorder (GAD) is the second least studied anxiety disorder and among the most difficult to treat. Dropout from psychotherapy is concerning as it is associated with poorer outcomes, leads to service inefficiencies and can disproportionately affect disadvantaged populations. No study to date has calculated a weighted mean dropout rate for GAD and explored associated correlates. METHODS A systematic review was conducted using PsycINFO, Medline and Embase databases, identifying studies investigating individual psychotherapies for adults with GAD. Forty-five studies, involving 2224 participants, were identified for meta-analysis. RESULTS The weighted mean dropout rate was 16.99% (95% confidence interval 14.42%-19.91%). The Q-statistic indicated significant heterogeneity among studies. Moderator analysis and meta-regressions indicated no statistically significant effect of client age, sex, symptom severity, comorbidity, treatment type, study type (randomized trial or not), study quality, number of sessions or therapist experience. CONCLUSIONS In research investigating psychotherapy for GAD, approximately one in six clients can be expected to drop out of treatment. Dropout rate was not significantly moderated by the client, therapist or treatment variables investigated. Future research should specify the definition of dropout, reasons for dropout and associated correlates to assist the fields progression.

Autobiographical memory specificity and general symptoms of anxiety: indirect associations through rumination

David John Hallford; David Mellor

ABSTRACT Depression is known to be associated with reduced autobiographical memory (AM) specificity; however, the relationship between anxiety symptoms and AM specificity has not been examined as thoroughly, with inconsistent findings. We sought to examine the association between general anxiety symptoms and AM specificity, and whether rumination and worry were potential mediators through which indirect associations may occur. Structural equation models were conducted using responses collected from 125 participants (M age = 26.3, SD = 3, 48.4% female) who completed the Autobiographical Memory Test, Rumination on Sadness Scale, the anxiety subscale from the Depression, Anxiety, and Stress Scale, the Penn State Worry Questionnaire, and the Patient Health Questionnaire. Higher anxiety symptoms, independent of depressive symptoms, were associated with reduced AM specificity through increased rumination. Worry was not a predictor of reduced AM specificity or a mediator of anxiety. The findings extend our understanding of the association between anxiety and reduced AM specificity, and suggest that rumination may represent a mediating pathway between psychopathology and effects on AM that is transdiagnostic in nature.

Staff Compliance With Protocols to Improve the Management of Behavioral and Psychological Symptoms of Dementia

David Mellor; Marita P. McCabe; Michael I. Bird; Tanya E. Davison; Sarah MacPherson; David John Hallford; Melissa Seedy

Using data from a larger study investigating the effectiveness of a structured clinical protocol to manage individuals in residential facilities who experience behavioral and psychological symptoms of dementia (BPSD), the current study investigated whether external clinical support in using the protocol with specific residents increased compliance in its use, over and above only providing a generic workshop about the protocol and management of BPSD. Results indicated that provision of the workshop, in addition to clinical support, was associated with significantly higher compliance. However, compliance was only found to be related to positive outcomes when staff received the generic workshop and not clinical support. When clinical support was provided, compliance was not related to outcomes or worse outcomes. These findings, when considered in the context of the results of the larger trial, suggest that the relationship among clinical support, compliance with BPSD protocols, and clinical outcomes for residents and staff is complex and needs further investigation.
