Caregiver expressed emotion as mediator of the relationship between neuropsychiatric symptoms of dementia patients and caregiver mental health in Hong Kong.

Objectives: Quality of life among Hong Kong's family dementia caregivers is a current heightened public health concern. This was one of the first East Asian studies to examine the role of family expressed emotion (EE) in the negative caregiver outcomes associated with dementia caregiving. EE comprises overinvolved and critical communications in families of people with mental illness. In this research, caregiver EE was evaluated as a mediator of the relationship between behavioral and psychological problems associated with dementia (BPSD) and negative caregiver outcomes.Method: Participants were 89 Hong Kong family caregivers (79% female, 84% married, 43% >50 years of age) of people with diagnosed dementia, recruited from elder day care centers. Caregivers completed the Neuropsychiatric Inventory (NPI), Cohen Mansfield Agitation Inventory (CMAI), Level of Expressed Emotion scale (LEE), Zarit Burden Interview, and Center for Epidemiological Studies Depression Scale (CES-D).Results: Agitation, delusions, hallucinations, aggression and irritability were BPSD most associated with caregiver burden and depression. EE significantly mediated the BPSD-negative caregiver outcome relationship. Among EE subscales, intrusiveness was significantly more common and less associated with negative caregiver outcomes. Caregiving hours, low family support, and religious nonaffiliation were associated with EE and poorer caregiver outcomes.Conclusions: The negative impact of BPSD on dementia caregivers in Hong Kong is influenced by EE. Higher scores on EE intrusiveness may be partly accounted for by filial piety, a strong sense of family responsibility characterized by high attentiveness to elderly family members. As EE is a potentially modifiable factor, interventions are considered.

Exploring Cultural Competence, Inclusivity, and Diversity in Ketamine Assisted Psychotherapy: A Phenomenological Study.

Black, Indigenous, and People of Color (BIPOC), and other minoritized populations are insufficiently represented in research on therapeutic psychedelics. This research was a phenomenological qualitative exploration of a culturally diverse (Hispanic, African American, Asian, Native American, biracial, or LGBTQIA+) and low-income sample of 15 individuals receiving ketamine-assisted psychotherapy (KAP) at a sliding-scale fee community clinic. Participants were interviewed after a ketamine session, after a ketamine integration session, and one month later. The interviews inquired about mental and emotional state prior to treatment and the treatment context (traditionally called set and setting), preparation for treatment, experiences during the ketamine and integration sessions, barriers to treatment, perceived stigma if any, reflections on KAPs' impact, and relevance of culture to the treatment. The current analysis, which focuses on participant comments related to diversity, equity, and inclusion that are uniquely relevant to this sample and the research goals, yielded four major themes: Insufficient Financial Resources, Race, Ethnicity, and LGBTQIA+, Stigma, and Culture and Ritual. Themes and subthemes are presented accompanied by representative quotes. Results demonstrate the high salience of culture in the KAP experience and the need to incorporate issues of race, culture, stigma, ritual, and socioeconomic status into treatment planning and outcome research.

Promoting optimal collaboration between mental health providers and nutritionists in the treatment of eating disorders.

The mental health provider-nutritionist collaboration is a primary partnership in the treatment of eating disorders, and its integrity is important for good patient care. Utilizing critical incident qualitative methodology, 22 professionals who specialize in the treatment of eating disorders (12 mental health providers, 10 registered dieticians) were interviewed about instances of problems in collaborations between these two professions, and the impact and resolution of such conflicts. Findings were used to compile a list of best practices. Results are interpreted with reference to research on professional health care teams in medical settings. Implications for interprofessional education and training are discussed.

Angry characters and frightened souls: Patients and family explanatory models of bipolar disorder in Taiwan.

Bipolar disorder (BD) affects a significant proportion of Taiwanese individuals (Weissman et al., 1996; Yang, Yeh, & Hwu, 2012). Psychotropic medications are typically the mainstay of treatment for BD, and there is an abundance of international research on biological etiology and medication options. However, there is comparatively little research on psychosocial aspects of BD, including how it is understood and managed within families. As culture provides the context in which psychiatric disease is managed, there is a need to identify distinct Chinese psychosocial perspectives that might shed light on intervention options. This research explored how Taiwanese patients and family members comprehend and cope with BD. A sample of 42 participants, including 20 Taiwanese patients diagnosed with Bipolar Disorder-I (BD-I) for at least 4 years, and 22 family members, participated in separate interviews on explanatory models of illness. Qualitative thematic analysis focused on features that were distinct from those in current Western research literature. Five themes were identified that represented Taiwanese conceptualizations of BD, notions of etiology, views regarding treatment, and the difficulties in managing the disorder. Participants used Chinese language terms and descriptions of BD that reflected greater concerns about irritability, anger, and family conflict than about other symptoms, and participants also emphasized characterological trait descriptions of the condition. Their responses reflected their acceptance of lifelong family responsibility for caretaking, clashing beliefs regarding biomedical versus traditional Chinese medical and spiritual models of etiology and cure, profound concerns about the effects of psychiatric medication on the liver and kidney systems, and a focus on stress rather than genetic or biological models of etiology.

Sleep impairment in patients with painful diabetic peripheral neuropathy.

OBJECTIVE: This study evaluated sleep impairment associated with painful diabetic peripheral neuropathy (DPN), a neuropathic pain condition. Sleep is of critical concern for DPN because sleep impairment and its comorbidities may influence type 2 diabetes progression. METHODS: This is a supplemental analysis of sleep data from a burden of illness study of patients with painful DPN (N=255, 61+/-12.8 y old, 51.4% women). Sleep was evaluated using the Medical Outcomes Study Sleep measure (MOS-Sleep). MOS-Sleep scores were compared with general population norms (N=1011), the MOS chronic disease sample (N=3445), and patients with postherpetic neuralgia (N=89). The MOS-Sleep Sleep Adequacy score was compared with data from the MOS diabetes subsample (N=590). RESULTS: Patients with painful DPN reported impaired sleep relative to the general population (P<0.001), the chronic disease sample (P<0.001), and postherpetic neuralgia patients (P<0.05). Self-rated MOS-Sleep Sleep Adequacy was significantly less for the painful DPN than for the diabetes sample (P<0.001), although self-reported hours of sleep were not significantly different. Multiple regression indicated that age, average daily pain, and anxiety and depression symptom levels were each significantly (P<0.01) associated with, and collectively accounted for, 47% of variance in the MOS-Sleep Sleep Problems Index. DISCUSSION: Painful DPN is associated with considerable sleep impairment. Given the recognized association between sleep impairment, type 2 diabetes and metabolic and affective disturbance, and the known adverse impact of affective disturbance on diabetes self-care, addressing these features-pain, sleep, and affective disturbance-is an important aspect of care for patients with painful DPN.

Categorizing the severity of cancer pain: further exploration of the establishment of cutpoints.

Previous work by Serlin and colleagues [Serlin R C, Mendoza T R, Nakamura Y, Edwards K R, Cleeland C S. When is cancer pain mild, moderate, or severe? Grading pain severity by its interference with function. Pain 1995;61:277-84] established cutpoints for mild, moderate, and severe cancer pain based on the pain's level of interference with function. Recent work [Jensen M P, Smith D G, Ehde D M, Robinson L R. Pain site and the effects of amputation pain: further clarification of the meaning of mild, moderate, and severe pain. Pain 2001;91:317-22; Zelman D C, Hoffman D L, Seifeldin R, Dukes, E. Development of a metric for a day of manageable pain control: derivation of pain severity cutpoints for low back pain and osteoarthritis. Pain 2003;106(1/2):35-42]found differences in cutpoints for pain severity for different pain-related conditions. Reasons for these discrepancies may relate to the methods used to determine the cutpoints or to differences based on the type or the cause of the pain. The purposes of this study were to determine the optimal cutpoints for mild, moderate, and severe pain based on patients' ratings of average and worst pain severity, using a larger range of potential cutpoints, and to determine if those cutpoints distinguished among the three pain severity groups on several outcome measures. Results from a homogenous sample of oncology outpatients with pain from bone metastasis confirm a non-linear relationship between cancer pain severity and interference with function and also confirm that the boundary between a mild and a moderate level of cancer pain is at 4 on a 0-10 numeric rating scale. However, this analysis did not confirm the boundary between moderate and severe cancer pain previously described by Serlin and colleagues [Serlin R C, Mendoza T R, Nakamura Y, Edwards K R, Cleeland C S. When is cancer pain mild, moderate, or severe? Grading pain severity by its interference with function. Pain 1995;61:277-84]. In addition, these results were not consistent with the cutpoints that were found for back pain, phantom limb pain, pain 'in general', or osteoarthritis pain reported by Jensen and colleagues and Zelman and colleagues [Jensen M P, Smith D G, Ehde D M, Robinson L R. Pain site and the effects of amputation pain: further clarification of the meaning of mild, moderate, and severe pain. Pain 2001;91:317-22; Zelman D C, Hoffman D L, Seifeldin R, Dukes, E. Development of a metric for a day of manageable pain control: derivation of pain severity cutpoints for low back pain and osteoarthritis. Pain 2003;106(1/2):35-42]. Possible explanations for these differences are discussed, as well as implications for future research.

Identification of cut-points for mild, moderate and severe pain due to diabetic peripheral neuropathy.

This study identified discrete categories of pain severity in a sample of patients with painful diabetic peripheral neuropathy (DPN), through derivation of cut-points on a 0-10 scale of pain severity (Brief Pain Inventory-DPN, BPI-DPN). Subjects were participants in a burden of illness survey (N=255). Serlin and colleagues' method establishing cut-points for cancer pain was adapted, considering all possible cut-points between 4 and 8. Optimal cut-points were those that created three pain severity categories producing maximum between-category differences on the seven BPI-DPN Interference items, using MANOVA. Cut-points of 4 and 7 optimally classified the sample for both Worst Pain and Average Pain, creating categories of mild, 0-3; moderate, 4-6; severe, 7 and higher (Hotelling's T(2)=22.95 and 16.20 for Worst and Average Pain, P<0.0001). Mean BPI-DPN Interference was 2.1 (SD=2.1), 4.9 (SD=1.9) and 7.4 (SD=1.6) for the mild, moderate and severe pain categories. Patients in the three categories differed significantly on patient-rated outcomes (Medical Outcomes Study Short Form-12v2 Mental and Physical Component Summaries and EuroQOL utility score), and on DPN-related healthcare visits (P<0.001). The labels 'mild, moderate and severe' Worst and Average Pain corresponded with patients' ratings of their pain using a verbal rating scale. This research shows that three categories of DPN pain severity can be identified based on interference with daily function, and that these categories are associated with patient outcomes and medical utilization.

Validation of a modified version of the brief pain inventory for painful diabetic peripheral neuropathy.

Neuropathic pain is the focus of current clinical research, clinical identification, and treatment. It is unique from nociceptive pain and requires evaluation of the relevance and utility of common pain measures created for other painful conditions. This study evaluated the psychometric properties of a modified Brief Pain Inventory (BPI) for patients with painful diabetic peripheral neuropathy (BPI-DPN). Participants were patients with painful DPN (n=255) enrolled in a DPN Burden of Illness survey referred through 17 outpatient settings (primary care physicians, endocrinologists, neurologists, and anesthesiologists). Patients completed the BPI-DPN, and self-report measures of health-related quality of life, mood sleep, and healthcare utilization. Construct, criterion and discriminant validity, and internal consistency reliability were evaluated. Principal axis factoring with oblimin rotation revealed two interpretable factors (eigenvalues>1.0), consistent with most published BPI validation studies; a severity scale comprising the four BPI Severity items and an interference scale comprising the seven Interference items, which satisfied criteria for interpretability and model fit. Cronbach's alpha was high (0.94) for both scales. Mean pain Severity was highly correlated with Bodily Pain from the Medical Outcomes Study Short Form-12, version 2 (rs=0.63, P < 0.001), the Pain/Discomfort item in the Euro-QoL (rs=0.58, P < 0.001), and a verbal rating scale measure of pain severity (rs=0.74, P < 0.001). Individual BPI-DPN Interference domains were moderately correlated (rs's >0.5, P < 0.001) with analogous measures, and the Sleep Interference item had a high, significant association with the three primary Medical Outcome Study-Sleep scale subscales (rs's=0.66-71, P < 0.001). Worst Pain and Interference ratings were significantly associated with hospital utilization and outpatient visits due to DPN. These results replicate, in a pure peripheral neuropathic pain condition, the BPI psychometric characteristics documented in populations with nociceptive or mixed pain conditions. The BPI-DPN is a promising instrument in the evaluation of painful DPN.

Cronbach's alpha was high (0.94) for both scales. Mean pain Severity was highly correlated with Bodily Pain from the Medical Outcomes Study Short Form-12, version 2 (r(s) = 0.63, P < .001), the Pain/Discomfort item in the Euro-QoL (r(s) = 0.58, P < .001), and a verbal rating scale measure of pain severity (r(s) = 0.74, P < .001). Individual BPI-DPN Interference domains were moderately correlated (r(s)'s > 0.5, P < .001) with analogous measures, and the Sleep Interference item had a high, significant association with the three primary Medical Outcome Study-Sleep scale subscales (r(s)'s = 0.66-71, P < .001). Worst Pain and Interference ratings were significantly associated with hospital use and outpatient visits because of DPN. These results replicate, in a pure peripheral neuropathic pain condition, the BPI psychometric characteristics documented in populations with nociceptive or mixed pain conditions. The BPI-DPN is a promising instrument in the evaluation of painful DPN.

Development of a metric for a day of manageable pain control: derivation of pain severity cut-points for low back pain and osteoarthritis.

The objective of this study was to adapt the concept of 'episode-free day', a metric for measuring symptom relief in daily units, to the clinical outcome literature for persistent pain. The episode-free day metric is widely used in other medical literature, but no analogous measure exists in pain literature. Prior focus groups with this population suggested that a 'Day of Manageable Pain Control' was an appropriate name for the metric. In the present study, in order to derive a statistical criterion for 'Manageable Day', we used Serlin et al.'s (Pain 61 (1995) 277) cut-point derivation method to derive a single cut-point on a 0-10 scale of average pain that divided groups with significant persistent pain optimally on pain-related functional interference. Participants were 194 patients with moderate-severe low back pain (n=96) or osteoarthritis (n=98). For both patient samples, '5' was the cut-point that optimally distinguished groups on pain-related interference. '5-8' and '5-7' were double cut-point solutions that optimally divided LBP and OA samples into three categories (e.g. lowest, medium and highest average pain), respectively. Derived cut-points were confirmed using a variety of measures of functional disability. Together with research that showed that average pain ratings of approximately 5 and below permit increased function and quality of life in patients with moderate to severe low back pain and osteoarthritis, our findings provide support for the use of 0-5 on a 0-10 numeric average pain severity scale as one possible criterion for a Manageable Day.

The effects of induced mood on laboratory pain.

Sixty-five subjects experienced 2 cold pressor immersions. Following the initial immersion, subjects participated in the Velten mood induction procedure by reading either depressive, neutral or elative statements. The sensory discriminative response to pain was measured by ratings of pain, and the affective-reactive response to pain was measured by pain tolerance. Pain tolerance, but not pain ratings, were affected by mood inductions with subjects in the depression condition shortening their tolerance times more than the subjects in the neutral condition and the subjects in the elative condition increasing their tolerance times.

Acceptable, manageable, and tolerable days: patient daily goals for medication management of persistent pain.

Although the construct of "a symptom-free day" has been widely applied in asthma and gastric reflux disease, there is no analogous concept in the field of pain management. This study represents the initial development of a "day of acceptable or manageable pain control," a construct which reflects patients' daily strategic use of pain medication in order to allow the accomplishment of desired activities while minimizing side effects. Focus group methodology was used to extract patient-generated themes of "an acceptable day of pain control." Fifty-three outpatients with persistent moderate to severe average pain intensity due to osteoarthritis (n=18), metastatic cancer (n=15), and low back pain (n=20) participated. Participants preferred the term "manageable" or "tolerable" to "acceptable." Thematic analysis revealed components of a manageable/tolerable day of pain control as including: 1) taking the edge off the pain, 2) performing valued activities; 3) relief from dysphoria and irritability; 4) reduced medication side effects; 5) feeling well enough to socialize. Additional cancer-specific themes included relief from fatigue and ability to have a positive day when one's future days were perceived as being limited. The set of themes is presented and their relevance for developing a measure of "a manageable day of pain control" discussed. Study findings identify a novel construct that can inform development of an outcome for evaluating the effectiveness of different pharmacotherapies for pain management.

Sleep disturbance is common among servicemembers and veterans of Operations Enduring Freedom and Iraqi Freedom.

Sleep routines that develop as an adaptation or reaction to deployment can persist upon return stateside. Sleep problems intensify and are intensified by psychiatric distress. This research presents the findings of a comprehensive survey of sleep impairment in relation to demographic data, military history, combat exposure, and mental illness symptoms among a general sample of 375 servicemembers and veterans of Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) at a wide range of times postdeployment. Sleep impairment was assessed with the Pittsburgh Sleep Quality Index (PSQI) and the Addendum for PTSD. Posttraumatic stress disorder (PTSD), depression, and anxiety symptoms were evaluated, with the PTSD Checklist-Military, the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7. Sleep problems were common across the sample, with 45.4% of participants reporting sleep onset greater than 30 minutes, 21.4% typically achieving less than 4.5 hours of total sleep time, and 56% reporting being awake in bed more than 15% of the night. Global PSQI scores classified 89% of the sample as "poor sleepers." Sleep problems were more severe among servicemembers with less education, from lower ranks (E1-E3), with greater combat exposure, and greater depression, anxiety, and PTSD symptoms. These findings suggest the need for routine screening of sleep problems among veterans and increased professional training in interventions for insomnia and nightmares. For individuals experiencing sleep problems with concurrent psychiatric symptoms, addressing sleep concerns may be one less-stigmatizing way to transition servicemembers and veterans into needed mental health services.

The attitudes of socially marginalized men toward physician-assisted suicide.

Bioethics and public policy literature suggests that socially marginalized populations may be at increased risk for overuse of physician-assisted suicide (PAS) were it to become more accepted. Yet the attitudes of socially marginalized populations toward PAS have not been widely studied. The present study surveyed a sample of men in a substance abuse recovery program. Participants completed a PAS attitude questionnaire and a religiosity measure. Support for PAS was fairly evenly split, with 52.2% indicating general opposition to PAS and 46.9% indicating general support. Greater religiosity was associated with more negative attitudes toward PAS. Higher educational level was associated with more acceptance. Overall attitudes toward PAS were considerably more negative than those of Dr. George Domino's (2003) general population sample.
