RESUMO
Impaired social functioning contributes to reduced quality of life and is associated with poor physical and psychological well-being in schizophrenia, and thus is a key psychosocial treatment target. Low social motivation contributes to impaired social functioning, but is typically examined using self-report or clinical ratings, which are prone to recall biases and do not adequately capture the dynamic nature of social motivation in daily life. In the current study, we examined the utility of global positioning system (GPS)-based mobility data for capturing social motivation and behavior in people with schizophrenia. Thirty-one participants with schizophrenia engaged in a 60-day mobile intervention designed to increase social motivation and functioning. We examined associations between twice daily self-reports of social motivation and behavior (e.g., number of social interactions) collected via Ecological Momentary Assessment (EMA) and passively collected daily GPS mobility metrics (e.g., number of hours spent at home) in 26 of these participants. Findings suggested that greater mobility on a given day was associated with more EMA-reported social interactions on that day for four out of five examined mobility metrics: number of hours spent at home, number of locations visited, probability of being stationary, and likelihood of following one's typical routine. In addition, greater baseline social functioning was associated with less daily time spent at home and lower probability of following a daily routine during the intervention. GPS-based mobility thus corresponds with social behavior in daily life, suggesting that more social interactions may occur at times of greater mobility in people with schizophrenia, while subjective reports of social interest and motivation are less associated with mobility for this population.

BACKGROUND: Social distancing measures meant to prevent the spread of COVID-19 in the past year have exacerbated loneliness and depression in the United States. While virtual tools exist to improve social connections, there have been limited attempts to assess community-based, virtual methods to promote new social connections. OBJECTIVE: In this proof-of-concept study, we examined the extent to which Skip the Small Talk (STST)-a business dedicated to hosting events to facilitate structured, vulnerable conversations between strangers-helped reduce loneliness in a virtual format in the early months of the 2020 COVID-19 pandemic. We predicted that participants who attended STST virtual events would show a reduction in loneliness, improvement in positive affect, and reduction in negative affect after attending an event. We were also interested in exploring the role of depression symptoms on these results as well as the types of goals participants accomplished by attending STST events. METHODS: Adult participants who registered for an STST virtual event between March 25 and June 30, 2020, completed a survey before attending the event (pre-event survey; N=64) and a separate survey after attending the event (postevent survey; n=25). Participants reported on their depression symptoms, loneliness, and positive and negative affect. Additionally, participants reported the goals they wished to accomplish as well as those they actually accomplished by attending the STST event. RESULTS: The four most cited goals that participants hoped to accomplish before attending the STST event included the following: "to make new friends," "to have deeper/better conversations with other people," "to feel less lonely," and "to practice social skills." A total of 34% (20/58) of participants who completed the pre-event survey reported depression symptoms that indicated a high risk of a major depressive episode in the preceding 2 weeks. Of the 25 participants who completed the pre- and postevent surveys, participants reported a significant reduction in loneliness (P=.03, Cohen d=0.48) and negative affect (P<.001, Cohen d=1.52) after attending the STST event compared to before the event. Additionally, depressive symptoms were significantly positively correlated with change in negative affect (P=.03), suggesting that the higher the depression score was prior to attending the STST event, the higher the reduction in negative affect was following the event. Finally, 100% of the participants who wished to reduce their loneliness (11/11) or feel less socially anxious (5/5) prior to attending the STST event reported that they accomplished those goals after the event. CONCLUSIONS: Our preliminary assessment suggests that the virtual format of STST was helpful for reducing loneliness and negative affect for participants, including those experiencing depression symptoms, during the COVID-19 pandemic. While encouraging, additional research is necessary to demonstrate whether STST has benefits when compared to other social events and interventions and whether such benefits persist beyond the events themselves.
RESUMO
BACKGROUND: People with schizophrenia and other serious mental illnesses often lack access to evidence-based interventions, particularly interventions that target meaningful recovery outcomes such as social functioning and quality of life. Mobile technologies, including smartphone apps, have the potential to provide scalable support that places elements of evidence-based interventions at the palm of patients' hands. OBJECTIVE: We aim to develop a smartphone app-called Motivation and Skills Support-to provide targeted social goal support (eg, making new friends and improving existing relationships) for people with schizophrenia enrolled in a stand-alone open trial. METHODS: In this paper, we presented preliminary outcomes of 31 participants who used the Motivation and Skills Support app for 8 weeks, including social functioning pre- to postintervention, and momentary reports of treatment targets (eg, social motivation and appraisals) during the intervention. RESULTS: The findings suggest that the intervention improved self-reported social functioning from baseline to treatment termination, particularly in female participants. Gains were not maintained at the 3-month follow-up. Furthermore, increased social functioning was predicted by momentary reports of social appraisals, including perceived social competence and the extent to which social interactions were worth the effort. CONCLUSIONS: The implications of these findings and future directions for addressing social functioning in schizophrenia using mobile technology have been discussed.

RESUMO
Abnormalities in resting-state electroencephalogram (rs-EEG) activity have been previously reported in schizophrenia. While most rs-EEG recordings were performed in patients with chronic schizophrenia during eyes closed (EC), only a handful of studies have investigated rs-EEG activity during both EC and eyes open (EO) conditions. It is also unknown whether EC and EO rs-EEG alterations are present at illness onset, and whether they change during the day. Here, we performed EC and EO rs-EEG recordings in the morning (AM) and evening (PM) in twenty-six first-episode psychosis (FEP) patients and seventeen matched healthy controls (HC). In AM/EC rs-EEG, a widespread reduction was found in low alpha power in FEP relative to HC. In PM/EC, the FEP group demonstrated a trend toward decreased theta power in parietal regions, while decreased high alpha power in frontal and left parietal regions was present during PM/EO. Moreover, reduced low alpha power during AM/EC was associated with worse positive symptoms. Altogether, those findings indicate that rs-EEG alterations are present in FEP patients at illness onset, that they are linked to the severity of their psychosis, and that distinct RS abnormalities can be detected in different conditions of visual alertness and time of the day. Future work should therefore account for those factors, which will help reduce variability of rs-EEG findings across studies and may serve as monitoring biomarkers of illness severity in schizophrenia and related psychotic disorders.

People with schizophrenia and schizoaffective disorder (SZ) often struggle with social impairment, including small social networks and loneliness. Limitations in social skills and reduced social motivation-effort to engage in social connection-are key contributors to social impairment. While evidence-based approaches to improving social outcomes are available, including social skills training and cognitive behavioral therapy for psychosis, ongoing access to these interventions is often limited. Mobile technologies, including smartphone applications (apps), may address some of this need. In this paper, we describe the development of a smartphone app designed to address social skill and motivation deficits in SZ: the Motivation and Skills Support (MASS) app. We discuss the incorporation of stakeholder input into intervention design as well as results from usability pilot testing of the app in a sample of people with SZ. Finally, we describe next steps in the development and testing process of the MASS app.
RESUMO
OBJECTIVE: To investigate the incidence of trampoline park injuries (TPIs) at a local recreational facility and to quantify the burden on emergency and orthopaedic services at our institute. METHODS: All patients that presented to the Emergency Department (ED) from the trampoline park via ambulance from July 2014 to November 2015 were included in the study. Patients' medical records were reviewed for clinical details including date, location and type of injury, treatment received, length of stay and outpatient follow-up. A cost analysis was performed to estimate the financial impact of each injury. RESULTS: A total of 71 patients were included in the study, with a mean age of 20 (7-48). Soft tissue sprains (n=29, 41%) and fractures (n=25, 35%) were the most common injuries, with the majority occurring in the lower limb. Two patients sustained open tibial fractures necessitating transfer to level 1 trauma centres. Fourteen patients (20%) underwent surgery, predominantly requiring open reduction and internal fixation. Overall, 18 patients (25%) required admission to hospital with mean length of stay of 2 days. The cost for pre-hospital, emergency and in-patient care amounted to over £80,000. CONCLUSION: TPIs pose a significant financial cost for local orthopaedic and emergency services. Contrary to studies evaluating home trampoline injuries, the majority of fractures at trampoline parks occurred in the lower limbs. Improved injury prevention strategies are required to help reduce morbidity and lower the financial implications for local NHS trusts.
RESUMO
BACKGROUND: Sleep disturbances are commonly reported in psychotic patients and often contribute to the manifestation and severity of their symptoms. Slow waves characterize the deepest stage of NREM sleep, and their occurrence is critical for restorative sleep. Slow wave abnormalities have been reported in patient with schizophrenia, especially when experiencing an exacerbation of psychosis. However, their presence and delineation, with an emphasis on topography, in first-episode psychosis patients (FEP) have not yet been characterized. METHODS: We performed sleep high density (hd)-EEG recordings in twenty FEP patients and twenty healthy control subjects (HC). Slow wave activity (SWA) and several other slow wave parameters, e.g. density, amplitude, up- and down-slopes, were calculated at each electrode location and compared across groups. Additionally, the association between slow wave characteristics and clinical symptoms was assessed. RESULTS: FEP patients showed a reduction selectively in slow-wave density relative to HC, and this reduction was significant in a large frontal area, including channels overlying the prefrontal cortex. Furthermore, slow wave density was inversely correlated with the severity of FEP positive symptoms. CONCLUSIONS: Abnormalities in slow waves are present at the beginning of psychosis, occur in frontal-prefrontal regions that are highly dysfunctional in psychotic patients, and are associated with their positive symptom severity. Building on these findings, future work will help establish the direction of these associations (i.e., if clinical symptoms precede, coincide, or follow SW deficits), which will determine whether ameliorating slow wave sleep deficits is a viable treatment target in early psychosis.

Aripiprazole is an antipsychotic drug characterized by partial agonist activity at D2 receptors to normalize both hyperdopaminergic and hypodopaminergic states. Traditional D2 antagonist antipsychotic drugs have been shown previously to reduce dopamine neuron activity through action on D2 autoreceptors to produce an overexcitation-induced cessation of cell firing, referred to as depolarization block. It is unclear whether aripiprazole reduces dopamine neuron activity via inhibition or, as seen following D2 antagonist administration, depolarization block. The impact of acute and repeated aripiprazole treatment was examined in the methylazoxymethanol acetate (MAM) rodent model to observe its effects on a hyperdopaminergic system, compared to normal rats. We found that administration of aripiprazole acutely or after 1 or 7 days of withdrawal from 21-day repeated treatment led to a decrease in the number of spontaneously active dopamine neurons in MAM rats but not in controls. This reduction was not reversed by apomorphine (100-200 µg/kg i.p. or 20 µg/kg i.v.) administration, suggesting that it was not due to depolarization block. In contrast, 1 h after induction of depolarization block of dopamine neurons by acute haloperidol treatment (0.6 mg/kg i.p.), aripiprazole (1 mg/kg, i.p.) reversed the depolarization block state. Therefore, aripiprazole rapidly reduced the hyperdopaminergic activity selectively in MAM rats. The reduction is unlikely due to depolarization block and persists following 7-day withdrawal from repeated treatment. Aripiprazole also removes haloperidol-induced depolarization block in MAM rats, which may underlie the acute psychotic state often observed with switching to this treatment.

OBJECTIVE: This study examined the physical and mental health of Cree adults, as well as the personal, clinical, and environmental factors associated with the presence of lifetime anxiety and mood disorders. METHODS: Mental health was assessed using the computerised version of the Diagnostic Interview Schedule (CDIS-IV), and standardised instruments were used to assess physical health, addiction severity, and psychological distress in 506 randomly selected participants from 4 Northern Cree communities in Quebec. RESULTS: Overall, 46.1% of participants reported chronic medical problems, 42.1% were current smokers and 34.5% met the DSM-IV criteria for an anxiety or mood disorder. Individuals with an anxiety or mood disorder were younger, predominantly female, and with higher educational levels, and a large proportion (47.7%) met the lifetime criteria for substance dependence. Hierarchical regression determined that anxiety or mood disorders were associated with serious problems getting along with parents, a history of physical and sexual abuse, and a lifetime diagnosis of substance dependence. Overall, 29.7% of Cree adults reported sexual abuse, 47.1% physical abuse, and 52.9% emotional abuse. CONCLUSIONS: This study highlights the high rates of physical and mental health problems in Cree communities and the association among parental history of psychological problems, history of abuse, and psychological distress. Participants expressed a desire for additional medical and psychological treatments to address the patterns of abuse, trauma, and mental disorders that are burdening the Cree communities in Northern Quebec.

Although the determination of pH is a standard laboratory measurement, new techniques capable of measuring pH are being developed to facilitate modern technological advances. Bio-industrial processing, tissue engineering, and intracellular environments impose unique measurement requirements on probes of pH. We describe a fiber optic-based platform, which measures the heat released by chromophores upon absorption of light. The optical fibers feature fiber Bragg gratings (FBG) whose Bragg peak redshifts with increasing temperature. Using anthocyanins (pH-sensitive chromophores found in many plants), we are able to correlate visible light absorption by a solution of anthocyanins to heat released and changes in FBG signal over a pH range of 2.5 to 10. We tested the ability of this platform to act as a sensor coating the fiber within a layer of crosslinked polyethylene glycol diacrylate (PEG-DA). Incorporating the anthocyanins into the PEG, we find that the signal magnitude increases over the observed signal at the same pH in solution. Our results indicate that this platform is viable for assessing pH in biological samples and point at ways to optimize performance.
RESUMO
Glioblastoma (GBM) is an aggressive and incurable primary brain tumor that causes severe neurologic, cognitive, and psychologic symptoms. Symptoms are caused and exacerbated by the infiltrative properties of GBM cells, which enable them to pervade the healthy brain and disrupt normal function. Recent research has indicated that although radiotherapy (RT) remains the most effective component of multimodality therapy for patients with GBM, it can provoke a more infiltrative phenotype in GBM cells that survive treatment. Here, we demonstrate an essential role of the actin-myosin regulatory kinase myotonic dystrophy kinase-related CDC42-binding kinase (MRCK) in mediating the proinvasive effects of radiation. MRCK-mediated invasion occurred via downstream signaling to effector molecules MYPT1 and MLC2. MRCK was activated by clinically relevant doses per fraction of radiation, and this activation was concomitant with an increase in GBM cell motility and invasion. Furthermore, ablation of MRCK activity either by RNAi or by inhibition with the novel small-molecule inhibitor BDP-9066 prevented radiation-driven increases in motility both in vitro and in a clinically relevant orthotopic xenograft model of GBM. Crucially, treatment with BDP-9066 in combination with RT significantly increased survival in this model and markedly reduced infiltration of the contralateral cerebral hemisphere.Significance: An effective new strategy for the treatment of glioblastoma uses a novel, anti-invasive chemotherapeutic to prevent infiltration of the normal brain by glioblastoma cells.Cancer Res; 78(22); 6509-22. ©2018 AACR.

Adverse childhood experiences (ACEs) and adult mental health were explored in a sample of urban Aboriginal ( n = 83) and non-Aboriginal ( n = 89) women. Childhood sexual abuse (CSA) was associated with negative home environments, teenage pregnancy, lifetime suicide attempts, and treatment seeking. Aboriginal women with CSA witnessed higher levels of physical/sexual abuse of family members. The severity of current psychological distress was associated with a history of childhood neglect. The results indicate that CSA rarely occurs in isolation, and that multiple ACEs are strongly associated with suicide attempts and treatment seeking in adulthood. Future studies should focus on the role of CSA in suicidality, as well as familial, community, and cultural protective factors.

The myotonic dystrophy-related Cdc42-binding kinases MRCKα and MRCKß contribute to the regulation of actin-myosin cytoskeleton organization and dynamics, acting in concert with the Rho-associated coiled-coil kinases ROCK1 and ROCK2. The absence of highly potent and selective MRCK inhibitors has resulted in relatively little knowledge of the potential roles of these kinases in cancer. Here, we report the discovery of the azaindole compounds BDP8900 and BDP9066 as potent and selective MRCK inhibitors that reduce substrate phosphorylation, leading to morphologic changes in cancer cells along with inhibition of their motility and invasive character. In over 750 human cancer cell lines tested, BDP8900 and BDP9066 displayed consistent antiproliferative effects with greatest activity in hematologic cancer cells. Mass spectrometry identified MRCKα S1003 as an autophosphorylation site, enabling development of a phosphorylation-sensitive antibody tool to report on MRCKα status in tumor specimens. In a two-stage chemical carcinogenesis model of murine squamous cell carcinoma, topical treatments reduced MRCKα S1003 autophosphorylation and skin papilloma outgrowth. In parallel work, we validated a phospho-selective antibody with the capability to monitor drug pharmacodynamics. Taken together, our findings establish an important oncogenic role for MRCK in cancer, and they offer an initial preclinical proof of concept for MRCK inhibition as a valid therapeutic strategy.Significance: The development of selective small-molecule inhibitors of the Cdc42-binding MRCK kinases reveals their essential roles in cancer cell viability, migration, and invasive character.

Despite high prevalence rates of concurrent borderline personality disorder (BPD) and substance use disorders (SUDs), little is known about the impact of substance misuse on the presentation of BPD. Sixty-five individuals with BPD were assessed at intake and at 3- and 6-month follow-up. Assessment included validated instruments such as the Addiction Severity Index and the Revised Symptom Checklist (SCL-90-R). Over half (58.5%) of individuals entering treatment were currently misusing substances. Substance misuse was associated with more legal and employment problems, greater mood disturbance, impulsivity, and psychiatric severity, including almost all SCL-90-R subscales. For the majority of patients (58%), there was little change in substance misuse post-treatment. The high prevalence of substance misuse and its association with psychiatric severity among individuals with BPD suggest that substance misuse should be a targeted behavior during treatment, and further specialized interventions are needed for individuals with comorbid BPD and SUD.

The methylazoxymethanol acetate (MAM) rodent neurodevelopmental model of schizophrenia exhibits aberrant dopamine system activation attributed to hippocampal dysfunction. Context discrimination is a component of numerous behavioral and cognitive functions and relies on intact hippocampal processing. The present study explored context processing behaviors, along with dopamine system activation, during fear learning in the MAM model. Male offspring of dams treated with MAM (20mg/kg, i.p.) or saline on gestational day 17 were used for electrophysiological and behavioral experiments. Animals were tested on the immediate shock fear conditioning paradigm, with either different pre-conditioning contexts or varying amounts of context pre-exposure (0-10 sessions). Amphetamine-induced locomotor activity and dopamine neural activity was measured 1-week after fear conditioning. Saline, but not MAM animals, demonstrated enhanced fear responses following a single context pre-exposure in the conditioning context. One week following fear learning, saline rats with 2 or 7min of context pre-exposure prior to fear conditioning also demonstrated enhanced amphetamine-induced locomotor response relative to MAM animals. Dopamine neuron recordings showed fear learning-induced reductions in spontaneous dopamine neural activity in MAM rats that was further reduced by amphetamine. Apomorphine administration confirmed that reductions in dopamine neuron activity in MAM animals resulted from over excitation, or depolarization block. These data show a behavioral insensitivity to contextual stimuli in MAM rats that coincide with a less dynamic dopamine response after fear learning.

Research has demonstrated that about 30% of chronic pain patients suffer from borderline personality disorder (BPD), yet pain is not often discussed in research on the treatment of BPD. Sixty-five patients entering outpatient treatment for BPD were assessed at baseline for the prevalence of DSM-IV lifetime pain disorder, current medical problems, and the experience of current pain as measured by the McGill Pain Questionnaire. DSM-IV lifetime pain disorder diagnosis was present in 65% of patients. Current pain was experienced by 89% of participants, with intensity ranging from mild (19%) to excruciating (2%). Some individuals (21.5%) also reported experiencing daily medical problems in the past month prior to entering treatment. Physical pain is highly prevalent among treatment-seeking individuals with BPD. This pain phenomenon should be considered during treatment to help prevent a lifetime of functional impairment, including the possibility of abusing substances as a maladaptive coping mechanism.

Aboriginal women in urban areas have been reported to experience high rates of poverty, homelessness, interpersonal violence, and health problems. However, there are few prior ethnocultural comparisons of urban women from similar socioeconomic backgrounds. The current study explored the mental and physical health of Aboriginal and non-Aboriginal women accessing social services agencies and shelters. Half of the sample (n=172) was Aboriginal (48.3%). The lifetime rate of physical abuse was significantly higher in Aboriginal women, and they were more likely to have been victims of violence or crime in the past year (A=50.6%, NA=35.6%, p<0.05). Rates of teenage pregnancy (<18 years of age) were significantly higher among Aboriginals (A=51.3%, NA=30.6%, p<0.05) and they reported more parental drug/alcohol problems (A=79.2%, NA=56.5%, p<0.05). Aboriginal women were also more likely to have previously received treatment for a drug or alcohol problem. There were no differences in self-reported physical health, medication use, hospitalisations, and current substance misuse. Irrespective of ethnicity, lifetime rates of anxiety, depression and suicide attempts were extremely high. Future research should explore the effects of individual resources (e.g. social support, family relations) and cultural beliefs on women's ability to cope with the stress of living with adverse events, particularly among low SES women with children.

BACKGROUND/AIMS: Traditionally, patients with acute diverticulitis undergo follow-up endoscopy to exclude colorectal cancer (CRC). However, its usefulness has been debated in this era of high-resolution computed tomography (CT) diagnosis. We assessed the frequency and outcome of endoscopic follow-up for patients with CT-proven acute diverticulitis, according to the confidence in the CT diagnosis. METHODS: Records of patients with CT-proven acute diverticulitis between October 2007 and March 2014 at Sandwell & West Birmingham Hospitals NHS Trust were retrieved. The National Cancer Registry confirmed the cases of CRC. Endoscopy quality indicators were compared between these patients and other patients undergoing the same endoscopic examination over the same period. RESULTS: We identified 235 patients with CT-proven acute diverticulitis, of which, 187 were managed conservatively. The CT report was confident of the diagnosis of acute diverticulitis in 75% cases. Five of the 235 patients were subsequently diagnosed with CRC (2.1%). Three cases of CRC were detected in the 187 patients managed conservatively (1.6%). Forty-eight percent of the conservatively managed patients underwent follow-up endoscopy; one case of CRC was identified. Endoscopies were often incomplete and caused more discomfort for patients with diverticulitis compared with controls. CONCLUSIONS: CRC was diagnosed in patients with CT-proven diverticulitis at a higher rate than in screened asymptomatic populations, necessitating follow-up. CT reports contained statements regarding diagnostic uncertainty in 25% cases, associated with an increased risk of CRC. Follow-up endoscopy in patients with CT-proven diverticulitis is associated with increased discomfort and high rates of incompletion. The use of other follow-up modalities should be considered.
RESUMO
BACKGROUND: Dislocation following primary total hip arthroplasty (THA) is a complication with an incidence of 2%-5%. This study examines the clinical and radiological outcome of a constrained acetabular implant used in primary THA in high-risk patients to prevent dislocation. METHODS: 54 patients with 55 constrained implants for primary THA were reviewed clinically and radiologically. Oxford, Harris Hip and Charlson scores were recorded. RESULTS: 54 patients, with an average age of 83.2 years, were followed up at a mean of 44.9 (20-74) months. 38 had an hydroxyapatite- (HA) coated acetabular shell with a constrained insert and 17 had a cemented constrained implant. The median Charlson score at surgery was 5 (4-10). There were significant improvements in Oxford, Harris hip pain and function scores and Charnley pain after surgery.2 patients had radiolucent lines on the most recent radiograph. Neither was symptomatic and the acetabular components had not migrated.3 patients developed postoperative infection, 1 deep requiring a 2-stage revision.Of the 29 patients who died, 1 required revision 2 months following surgery for dislocation of the constrained liner. This patient died 26 months later from unrelated causes having had no further complications from her surgery. There have been no further revisions or reoperations for dislocation in any of the other cases. CONCLUSIONS: The use of a constrained acetabular liner at primary THA in high risk patients for dislocation can successfully prevent this complication without increasing component loosening. In this series of 55 constrained implants we have a postoperative dislocation rate of 1.8%.

A detailed survey of gambling, addiction and mental health was conducted with randomly selected respondents (n = 506) from four Cree communities of Northern Quebec. The study examined the current patterns of gambling in relation to demographic, social, and psychological factors. Instruments included the Canadian Problem Gambling Index, Addiction Severity Index, Beck Depression Inventory and the computerized Diagnostic Interview Schedule for psychiatric diagnoses. Overall, 69.2 % of the total sample participated in any gambling/gaming activities over the past year; 20.6 % of this group were classified as moderate/high risk gamblers, and 3.2 % were classified in the highest "problem gambling" category. Considering the entire sample, the overall prevalence of problem gambling was 2.2 %. Women were significantly more likely to play bingo (56.6 %) compared to men (35.1 %) and they played more frequently; 20.8 % of women versus 3.8 % of men played once/week or more often. Compared to the no/low risk gamblers, a greater proportion of moderate/high risk gamblers were cigarette smokers (44.8 vs. 56.3 %), they were more likely to meet DSM-IV diagnostic criteria for alcohol dependence (21.2 vs. 46.2 %), and they were more likely to report moderate to severe depressive symptoms in the past month. Risk factors for problem gambling included traumatic life events (physical and emotional abuse), anxiety and depression, as well as drug/alcohol abuse. The high rates of comorbidity between problem gambling, tobacco dependence, substance abuse and other psychological problems demonstrate that gambling among some Cree adults is part of a pattern of high-risk factors for negative long-term health consequences. The results also have implications for treatment, suggesting that interventions for gambling disorders should not focus on gambling alone but rather the constellation of high-risk behaviours that pose a risk to recovery and well-being.
