Predictive modeling of initiation and delayed mental health contact for depression.

BACKGROUND: Depression is prevalent among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) Veterans, yet rates of Veteran mental health care utilization remain modest. The current study examined: factors in electronic health records (EHR) associated with lack of treatment initiation and treatment delay; the accuracy of regression and machine learning models to predict initiation of treatment. METHODS: We obtained data from the VA Corporate Data Warehouse (CDW). EHR data were extracted for 127,423 Veterans who deployed to Iraq/Afghanistan after 9/11 with a positive depression screen and a first depression diagnosis between 2001 and 2021. We also obtained 12-month pre-diagnosis and post-diagnosis patient data. Retrospective cohort analysis was employed to test if predictors can reliably differentiate patients who initiated, delayed, or received no mental health treatment associated with their depression diagnosis. RESULTS: 108,457 Veterans with depression, initiated depression-related care (55,492 Veterans delayed treatment beyond one month). Those who were male, without VA disability benefits, with a mild depression diagnosis, and had a history of psychotherapy were less likely to initiate treatment. Among those who initiated care, those with single and mild depression episodes at baseline, with either PTSD or who lacked comorbidities were more likely to delay treatment for depression. A history of mental health treatment, of an anxiety disorder, and a positive depression screen were each related to faster treatment initiation. Classification of patients was modest (ROC AUC = 0.59 95%CI = 0.586-0.602; machine learning F-measure = 0.46). CONCLUSIONS: Having VA disability benefits was the strongest predictor of treatment initiation after a depression diagnosis and a history of mental health treatment was the strongest predictor of delayed initiation of treatment. The complexity of the relationship between VA benefits and history of mental health care with treatment initiation after a depression diagnosis is further discussed. Modest classification accuracy with currently known predictors suggests the need to identify additional predictors of successful depression management.

Original Research: What Health Care Staff Who Experienced Assisted Patient Falls Can Teach Us: Implications for Fall and Fall Injury Risk.

PURPOSE: This quality improvement project had three aims: to identify common assisted falls scenarios, describe staff members' experiences with and risk perceptions of such falls, and explore factors that influenced their perceptions. The overarching goal was to gain useful insight for the development of assisted fall-related strategies and policies. METHODS: In the fall of 2020, 16 staff members from 13 health care facilities were purposively recruited and interviewed. Transcript summaries of these interviews, along with secondary narrative data from employee and patient injury databases, were analyzed using thematic content analysis. RESULTS: According to staff members' accounts, assisted falls most commonly took place in patient rooms or bathrooms when patients were ambulating or transferring. The interviewees described assisting falls by grabbing or holding the patient or by using their own body to brace or steady the patient. Interview and secondary narrative data noted various injuries that occurred during assisted fall events. These injuries most often involved the lower back (among staff) and the legs (among patients). Most interviewees perceived that using proper body mechanics would prevent injury. CONCLUSIONS: Interviewees' experiences with assisted falls indicate areas of improvement for fall prevention. The perception that using proper body mechanics will protect staff from injury may be a misconception. Although the literature reports mixed findings concerning whether staff should assist patient falls, this project's results led us to conclude that there is no safe way to physically assist a falling patient without risk of staff injury.

Staff Low Back Injury Risk During Assisted Falls Virtual Reality Simulations.

BACKGROUND: Assisted falls occur when staff try to minimize the impact of falls by slowing a patient's descent. Assisting a patient fall may decrease patient injury risk, but biomechanical risk of injury to staff has not been evaluated. Assisted falls virtual reality (VR) simulations were conducted to examine staff low back injury risk during common assisted falls scenarios. METHODS: VR simulations of a toilet to wheelchair transfer were developed with a male patient avatar for three assisted falls scenarios: standing up from toilet, sitting down on wheelchair, and ambulation. Patient avatar weight was modified to reflect normal, underweight, and overweight adult patients. The average spinal compression force at L5/S1 was calculated for each participant with five trials per three scenarios while utilizing physical ergonomic techniques and compared to the safe spinal compression limit of 3,400 Newtons (N). FINDINGS: Six staff participants completed 90 VR simulations in total. The average calculated spinal compression force ranged from 7,132 N to 27,901 N. All participant trials exceeded the safe spinal compression limit of 3,400 N for every assisted falls scenario and avatar weight despite application of ergonomic techniques including wide stance, knees bent, and backs straight. CONCLUSIONS/APPLICATION TO PRACTICE: Staff are at risk for low back injury if they assist falls regardless of the adult patient weight and application of ergonomic techniques. Safer alternatives like the implementation of mobility screening tools and safe patient handling and mobility technology are needed to help prevent assisted falls to decrease injury risk to both patients and staff.

Reliability and validity of the Veterans Administration Mobility Screening and Solutions Tool.

OBJECTIVES: The Veterans Administration (VA) Mobility Screening and Solutions Tool (VA MSST) was developed to screen a patient's safe mobility level 'in the moment' and provide clinical decision support related to the use of safe patient handling and mobility (SPHM) equipment. This evidence-based flowchart tool is a common language tool that enables any healthcare worker at any time to accurately measure and communicate patient mobility and transfer equipment needs across disciplines and settings. METHODS: The VA MSST has four levels and differentiates between the need for powered and non-powered equipment depending on the patient's independence. Subject matter experts wrote scenarios for interrater reliability and validity testing. The initial VA MSST draft iteration was reviewed by 163 VA staff (mostly physical therapists and occupational therapists) amongst simulation scenarios and provided content validity, and additional insight and suggestions. Revisions were made to create the final VA MSST which was evaluated by over 200 healthcare workers from varied disciplines (including medical doctors, advanced practice registered nurses, registered nurses, licensed practical nurses, certified nursing assistants, occupational therapists, physical therapists, speech therapists, radiology and ultrasound technicians, etc.). An instruction video and eighteen scenario videos were embedded in an online survey. The survey intended to demonstrate the interrater reliability and validity (concurrent and construct) of the VA MSST. Over 500 VA staff (raters) received a survey invitation via email. RESULTS: Raters (N = 230) from multiple disciplines and healthcare settings independently screened patient mobility status for each of 18 scenarios using the VA MSST. The raters were diverse in their age and years of experience. The estimated interrater reliability (IRR) for VA MSST was excellent and statistically significant with an estimated Krippendorff's alpha (ICC (C, k)) of 0.998 [95% CI: 0.996-0.999]. Eighty-two percent of raters reported that overall VA MSST instructions were clear or very clear and understandable. VA MSST ratings made by technicians and nursing assistants group correlated strongly (r = 0.99, p < 0.001) with the 'gold standard' (experienced physical therapists), suggesting a high concurrent validity of the tool. The VA MSST significantly discriminated between the different levels of patient mobility required for safe mobilization as intended (each difference, p < 0.0001); this suggests a good construct validity. CONCLUSIONS: The VA MSST is an evidence-based flowchart screening and decision support tool that demonstrates excellent interrater reliability across disciplines and settings. VA MSST has strong face and content validity, as well as good concurrent and construct validity.

Evaluation of a new assistive technology: the StandBar.

PURPOSE: Evaluate the potential of a wheelchair assistive technology (StandBar) to promote power wheelchair users' ability to safely stand independently from their power wheelchair and determine the impact of the device use on psychological well-being for both power wheelchair users and their caregivers. MATERIALS AND METHODS: A convenience sample of 11 power wheelchair users and caregiver dyads provided study data. Participants included power wheelchair users who were existing StandBar users or currently in training with the StandBar as part of their rehabilitation. Assessments were conducted at baseline and at six-month follow-up and included physiological assessments and functional testing with and without the StandBar. Monthly follow-up phone calls were completed to collect information on adverse events (e.g., falls, hospitalizations, and skin breakdown). A qualitative interview assessed StandBar users' and caregivers' perception at six-month follow-up. RESULTS AND CONCLUSIONS: StandBar use provided power wheelchair users a higher level of independence, confidence, and safety. All participants highly recommended StandBar use to others with similar levels of functional impairment. StandBar use allowed many participants the ability to complete functional tasks that were otherwise not possible without assistance. Qualitative interviews reported improved independence and psychological well-being for StandBar users as well as reduced levels of anxiety and burden of care by caregivers. The StandBar is a cost-effective assistive technology that promotes independence and functionality for power wheelchair users and improves the psychological well-being of users and their caregivers. Implications for RehabilitationStandBar allows power wheelchair users to:Minimize negative effects of immobilization.Increase independence for activities of daily living (grooming, hygiene, toileting, transfers) and instrumental activities of daily living (social experiences).Improve their quality of life through increasing independence and confidence.Reduce need for assistance and corresponding caregiver burden.

Concussion coach for postconcussive symptoms: A randomized, controlled trial of a smartphone application with Afghanistan and Iraq war Veterans.

Objective: Investigate the effectiveness of Concussion Coach, an interactive smartphone application, as a treatment for residual neurobehavioral symptoms and distress in Veterans with a history of mild traumatic brain injury (mild TBI). Methods: Veterans with mild TBI were randomized to Concussion Coach (n = 238) or Treatment-as-Usual (TAU) (n = 241) in a 3-month randomized controlled trial. Primary outcome measures included postconcussive symptom (PCS) severity as measured by the Neurobehavioral Symptom Inventory (NSI), and psychological distress as measured by the Brief Symptom Inventory-18 (BSI-18). Measures of self-efficacy, social support, and comfort with technology were administered as potential moderators and mediators. An intention-to-treat (ITT) analysis was performed (N = 461: Concussion Coach = 231 and TAU = 230) using Bayesian Network (BN)modeling. Results: The probability of decreased PCS severity was significantly greater for those assigned to Concussion Coach, .35 [.32,.37], than for TAU, .29 (.27, .32), with an odds ratio (OR) of 1.29. Also, Concussion Coach showed a significantly greater probability of increased self-efficacy (.36 [.32, .39]) than did TAU (.28 [.25, .30], OR = 1.42). In turn, self-efficacy (increased vs. decreased) showed a significantly greater probability of decreased PCS severity (.51 [.47, .54] vs. .27 [.24, .30], OR = 2.71) and decreased psychological distress (.53 [.49, .56] vs. .32 [.29, .35], OR = 2.35), suggesting that self-efficacy may have mediated Concussion Coach effects. Conclusions: Concussion Coach is effective at reducing PCS severity and psychological distress. Increased self-efficacy/perception of self-management of symptoms may be key to successful treatment of residual symptoms in those with history of concussion.

Evaluation of Protective Properties of Commercially Available Medical Helmets: Are Medical Helmets Protective?

OBJECTIVES: The aims of the study were to evaluate and to compare protective properties of commercially available medical helmets for a set of standardized head injury risk measures. METHODS: Eleven helmet types were evaluated to represent the variety of commercially available medical helmet designs and manufacturers. A test mannequin and sensor apparatus were used to simulate a backward-standing fall. The head/neck size, mass, and "standing" height of the mannequin (5'9″) were representative of a 50th percentile male. A triaxial array was placed at the head center of mass to position 3 linear accelerometers and 3 angular rate sensors. Data were collected for 5 single trials for each helmet, as well as 5 repeated trials. Five trials were also collected with no helmet scenarios. Three head injury risk measures were examined (linear acceleration, angular acceleration, and head injury criterion). Data were analyzed by clinical cutoff thresholds and continuous values. RESULTS: Helmets varied in their performance across head injury risk measures. All helmets provided higher levels of protection compared with no helmet scenarios. No helmets were protective for subdural hematoma (measured by angular acceleration). All helmets lost protective properties with repeated falls. Results for skull fracture risk were inconsistent between linear acceleration and head injury criterion injury risk measures. CONCLUSIONS: No helmets were protective across all head injury risk measures. Medical helmets may reduce some fall injury severity but may not prevent all types of head injury. All helmets exhibited worsening of protective properties with repeated falls. We recommend medical helmets be replaced after each fall incident where the helmet impacts another surface.

A preliminary evaluation of full practice authority of advance practice registered nurses in the Veterans Health Administration.

BACKGROUND: Responding to National Academy of Medicine and National Council of State Boards of Nursing recommendations, the Department of Veterans Health Affairs (VHA) implemented full practice authority (FPA) for Advanced Practice Registered Nurses in VHA medical centers (VAMCs) in 2017. PURPOSE: To evaluate FPA policy implementation's impact on quality indicators including access to care as measured by new patient appointments in primary, specialty and mental health services. METHODS: Linear growth models compared early (n = 85) vs. late (n = 55) FPA implementing VAMCs on the trajectories of each of the three quality indicators. FINDINGS: Early FPA implementing VAMCs showed greater rates of improvement over time in new patient appointments completed within 30 days of preferred date for primary care (p = .003), specialty care (p = 0.05), and mental health (p = 0.001). DISCUSSION: VAMCs that started implementation of FPA policy early showed greater improvement in access to care for Veterans over time than VAMCs that did not.

Doctoral-prepared nurses in the Veterans Health Administration: A cross-sectional survey.

BACKGROUND: Doctoral-prepared nurses with diverse skillsets are required to meet nursing care needs in a complex and changing healthcare environment. A better understanding of the roles of doctoral-prepared nurses in Veterans Health Administration (VHA) workforce will help leverage their expertise to meet the needs of Veterans. PURPOSE: Assess the current roles of doctoral-prepared nurses within the VHA. METHOD: A cross-sectional survey was used to collect information on doctoral-prepared nurses within the VHA in 2016. Multiple strategies were used to identify doctoral-prepared nurses to recruit for an online survey. Survey invitations were sent electronically to unique individuals identified (N = 2403). RESULTS: Responses were received from 1015 nurses (42.2% response rate), with 929 nurses with a doctoral degree identified. DNP/DNAP degrees were most common (55%), followed by a PhD or DNS (33%). Significant differences were noted between nurses in different doctoral education categories across four main roles: research, clinical, educational, and administration. CONCLUSIONS: This survey generated the first comprehensive list of VHA doctoral-prepared nurses. Findings are being used by the VHA Office of Nursing Services to align degree types, duties of different positions, functional statements, and position expectations. Results support the continued need for collaboration between nurses with PhDs and DNPs to achieve research and clinical goals.

Mortality and Associated Risk Factors in Community-Dwelling Persons With Early Dementia.

OBJECTIVE: Examine mortality and associations with baseline characteristics among Veterans with early dementia. METHODS: Participants included dyads of community-based Veterans with early dementia and their caregivers (N=143) enrolled in a previous longitudinal study. Department of Veterans Health Affairs' electronic records were used to retrospectively collect Veteran mortality outcomes, over a 6-year period. Measures included baseline: demographics, dementia-related factors, other comorbid conditions, functioning, and medication use. Associations with baseline characteristics and mortality were examined with bivariate analyses and a series of Cox proportional hazard models. RESULTS: Over 6 years of study follow-up, 53.1% of participants died. The mean time to death was 3.09 years, with a range of 54 days to 5.91 years. Female sex, better cognition, and higher scores on the Tinetti Gait and Balance scale were protective factors in the final multivariable model, adjusting for other characteristics. CONCLUSIONS: While newly diagnosed with early dementia, over half of our sample died in the 6-year follow-up period, with the average death occurring only 3 years after initial diagnosis. The finding of lower mortality associated with better performance on gait/balance testing indicates an important opportunity for focused interventions and early detection of gait and balance changes early during cognitive decline.

One hertz versus ten hertz repetitive TMS treatment of PTSD: A randomized clinical trial.

The purpose of this trial was to test whether right prefrontal cortex 1 Hz versus 10 Hz rTMS provides a significantly greater improvement in PTSD symptoms and/or function. Veterans 18 to 50 years of age suffering from PTSD were randomized to right prefrontal 1 Hz rTMS [2400 pulses/session] versus right prefrontal 10 Hz rTMS [2400 pulses/session]. The treatments were performed 5 days a week for 6 weeks with a 3-week taper using the NeuroStar system. There were one month and three months post treatment follow-up evaluations. Forty-four participants were enrolled with 17 being randomized to 1 Hz rTMS and 18 to 10 Hz rTMS. Both groups had significant improvement in PTSD and depression scores from baseline to the end of acute treatment. The 10 Hz group but not the 1 Hz group demonstrated significant improvement in function. Although both groups demonstrated significant improvement in PTSD and depression symptoms, a significant advantage for either the 1 Hz or 10 Hz frequency group on any of the scales acquired was not demonstrated. Further work is required with larger samples sizes to test whether low or high frequency is superior or if individual differences would indicate the more effective frequency.

Factors Associated With Wandering Behaviors in Veterans With Mild Dementia: A Prospective Longitudinal Community-Based Study.

OBJECTIVE: To investigate baseline factors associated with caregiver-reported wandering among community-dwelling veterans with mild dementia. METHODS: Veterans with mild dementia (N = 143) and their caregivers participated in a 2-year prospective longitudinal study. Measures assessed wandering, daily function, behavior, cognition, and personality features. Wandering was dichotomized as present or absent across study periods, and associations with baseline characteristics were examined. RESULTS: One-quarter of participants demonstrated caregiver-reported wandering at 1 or more study visits, with 14% to 15% wandering at any 1 visit. Wandering was associated with significantly lower baseline scores in performance of daily function, behavioral response to stress, gait, and balance, and conscientiousness. CONCLUSIONS: This novel study evaluated wandering in a community-dwelling sample of veterans with mild dementia. Wandering was associated with a specific personality trait, poorer behavioral response to stress as well as greater functional and gait/balance impairment. These findings may assist in developing community-based interventions for caregivers.

What makes a peer a peer?

OBJECTIVE: The purpose of this study was to learn more about which characteristics are considered important for consumers to feel that a person is their peer. METHODS: Forty-one participants in a jail diversion program for veterans were asked to rate characteristics in terms of importance for acting in a peer support role. Differences by gender, combat exposure, trauma history, and mental health and substance abuse treatment were analyzed using t tests and Pearson correlations. RESULTS: Having served in the military had the highest average rating; trauma experience second. Participants with combat experience were significantly more likely than those without to indicate this as an important characteristic. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Increasingly behavioral health programs are recognizing the importance of peer involvement. This study offers guidance on who should be designated a "peer," suggesting that this should vary according to the population served and be based on the perceptions of the consumers.

The role of positive alcohol expectancies in underage binge drinking among college students.

OBJECTIVE: This study explored associations between positive alcohol expectancies, and demographics, as well as academic status and binge drinking among underage college students. PARTICIPANTS: A sample of 1,553 underage college students at 3 public universities and 1 college in the Southeast who completed the Core Alcohol and Drug Survey in the Spring 2013 semester. METHODS: A series of bivariate analyses and logistic regression models were used to examine associations between demographic and academic status variables as well as positive alcohol expectancies with self-reported binge drinking. Positive alcohol expectancies were examined in multivariable models via 2 factors derived from principal component analyses. RESULTS: Students who endorsed higher agreement of these 2 emergent factors (sociability, sexuality) were more likely to report an occurrence of binge drinking in the past 2 weeks. CONCLUSIONS: Study results document associations between positive alcohol expectancies and binge drinking among underage students; implications for prevention and treatment are discussed.

College students who endorse a sub-threshold number of DSM-5 alcohol use disorder criteria: alcohol, tobacco, and illicit drug use in DSM-5 diagnostic orphans.

OBJECTIVES: Diagnostic orphans (DOs) represent a group of individuals with no formal diagnosis, despite endorsing some criteria of an alcohol use disorder (AUD). Prior research has indicated that rates of DSM-IV DOs in college are high and closely resemble those with an alcohol abuse diagnosis across pertinent alcohol use risk factors. However, significant changes to the DSM-IV AUD criteria have been made for the current DSM-5 manual, which may impact how DOs are classified. This study examined the unique alcohol and illicit drug use characteristics of a group of 2,620 DSM-5 DOs in college and tested whether DOs differed from those with and without a DSM-5 AUD across pertinent alcohol and drug use risk factors. METHODS: Participants were 2,620 DSM-5 DO undergraduate college students, between the ages of 18 and 30, recruited from three public universities in the Southeastern, United States. RESULTS: Diagnostic orphans represented 19.6% (n = 506) of the sample; with the most frequently endorsed criteria being tolerance and consuming alcohol in hazardous situations. DOs reported significantly greater alcohol consumption, alcohol and drug related problems, and illicit drug use compared to those with no DSM-5 AUD diagnosis. Alternatively, DOs reported significantly lower alcohol use and illicit drug use compared to those with a DSM-5 AUD. CONCLUSION: The present findings indicate that DSM-5 DOs in college represent a distinct group of drinkers relative to those with and without a DSM-5 AUD. Current screening initiatives should target this group to prevent future escalation of problem drinking.

Six-month outcomes of an integrated assertive community treatment team serving adults with complex behavioral health and housing needs.

Assertive community treatment (ACT) and integrated dual disorders treatment (IDDT) have individually proven effective for treatment of adults with complex behavioral health and housing needs. This study evaluated the effectiveness of an ACT team that delivered integrated care consistent with IDDT principles. Participants included 60 adults with a history of chronic homelessness and co-occurring mental health and substance use disorders. Measures assessing mental health, substance use, and residential stability were completed at intake to the program and then 6 months later. Participants reported statistically significant improvements in mental health symptomatology and residential stability over time, although there were no changes in substance use. Findings support the effectiveness of the intervention for improving mental health and housing stability among adults with complex behavioral health and housing needs. Fidelity data support the notion that multiple evidence-based interventions can be integrated while still maintaining adequate fidelity to individual components.

Clinical history and characteristics of persons with oxycodone-related deaths in Hillsborough County, Florida in 2009.

AIMS: To analyze toxicological findings of accidental deaths involving oxycodone to determine demographic characteristics and clinical histories. METHODS: Accidental deaths in which oxycodone was mentioned as a cause of death were analyzed. The sample included all persons deceased in Hillsborough County in 2009 where oxycodone was present. The entire sample was divided into two subgroups listing oxycodone as the primary/contributory cause of death (n=117) or oxycodone as the incidental cause of death (n=38). Differences between the two groups in demographic and clinical history variables as well as the presence and concentration of drugs were examined. RESULTS: The majority of decedents within the entire sample (N=155) were Caucasian males (58.1%) aged 50 or older. More than half of the population (52.9%) did not hold prescriptions for oxycodone. Those who died with a primary/contributory cause of death were younger, more likely to have a history of substance abuse, and more likely to have alprazalom (Xanax) present in their system. Across the entire sample, the mean oxycodone concentration level was 0.40 mg/L, with a range from 0.02 to 3.70 mg/L. Those who died with a primary/contributory cause of death had a significantly higher level of mean oxycodone concentration than those with an incidental cause of death, 0.48 mg/L compared to 0.16 mg/L. CONCLUSIONS: Results suggest that the demographic findings mirror statewide and national trends. In general, mean oxycodone concentration levels were shown to be lower than those previously reported in literature. Overlap and range of concentrations between those with a primary/contributory and incidental cause of death demonstrates the significance of individual case history and tolerance in the interpretation of postmortem drug concentrations when determining cause and manner of death.

Recovery orientation of treatment, consumer empowerment, and satisfaction with services: a mediational model.

OBJECTIVE: This study explores the relationship between the recovery orientation of treatment and subjective experiences of consumer empowerment and satisfaction with services for individuals with severe and persistent mental illness. METHODS: Instruments measuring perceptions of empowerment, recovery orientation of treatment, and satisfaction with services were administered to 45 participants enrolled in two demographically similar mental health treatment programs in Tampa, Florida - a community mental health center and an Assertive Community Treatment team. Analyses were conducted according to traditional mediation models. Empowerment was expected to mediate the relationship between the recovery orientation of treatment and consumer satisfaction with services. RESULTS: A recovery-based treatment orientation significantly predicted both consumer empowerment and satisfaction with services. Empowerment mediated the relationship between treatment orientation and consumer satisfaction. CONCLUSIONS: These preliminary findings highlight the impact of the recovery orientation of treatment on empowerment and satisfaction with services among individuals with severe and persistent mental illness.

Factors predicting arrest for homeless persons receiving integrated residential treatment for co-occurring disorders.

BACKGROUND: Homeless individuals are at increased risk for health and criminal justice problems. AIMS: The aim of this study was to examine risk factors affecting arrest rates in a cohort of homeless people with co-occurring psychiatric and substance-abuse disorders. METHODS: Baseline data were collected from 96 homeless individuals residing in a residential treatment facility for people with co-occurring disorders. Arrest data were obtained for 2 years following treatment intake. Regression analyses were employed to examine interactions between study variables. RESULTS: One third of the sample was arrested during the 2-year follow-up period, principally for drug offences. People referred to treatment directly from the criminal justice system were four times more likely to re-offend than those referred from other sources. Participants' perceived need for mental-health services reduced risk of arrest while their perception of medical needs increased this risk. CONCLUSIONS: The relationship between referral from a criminal justice source and re-arrest after admission to the treatment facility is unsurprising, and consistent with previous literature, but the suggestion of an independently increased risk in the presence of perceived physical health-care needs is worthy of further study. The lower risk of arrest for people who perceive that they have psychological needs is encouraging.
