Complete quasilinear model for the acceleration-driven lower hybrid drift instability and a computational assessment of its validity.

A complete quasilinear model is derived for the electrostatic acceleration-driven lower hybrid drift instability in a uniform two-species low-beta plasma in which current is perpendicular to the background magnetic field. The model consists of coupled nonlinear velocity space diffusion equations for the volume-averaged ion and electron distribution functions. Each species' diffusion coefficient depends on a time-evolving spectral density of the electric-field energy per unit volume and a time-evolving dispersion relation.

The integrated behavioral model of mental health help seeking (IBM-HS): A health services utilization theory of planned behavior for accessing care.

This article introduces the integrated behavioral model of mental health help seeking (IBM-HS), a theoretical model for understanding the constructs (e.g., systemic, predisposing, and enabling factors; mental health literacy; illness perceptions; perceived need; stigma; shame; perceived benefits, motivation) that influence people's decision making around seeking professional mental health care and their ultimate access to formal treatment.

What Attributes of Integrated Health Care for Mental Health Are the Most Important to Potential Consumers? A Relative Ranking Study.

Integrated health care (IHC) is efficacious, cost-effective, and more attractive to some consumers than traditional standalone psychotherapy, but the specific characteristics of IHC that drive this enhanced attraction have yet to be explored among potential future mental health consumers. As such, this brief report documents the results of a survey of 428 US adults who were asked to rank order the relative personal importance of seven characteristics (e.g.

Reputable and affordable programs with a strong commitment to diversity: Factors influencing school psychology student admission decisions.

A current issue in the field of school psychology is the extreme shortage of school psychologists, and this is likely to persist in the future. Effective recruitment into school psychology programs is one of the most important strategies to increase the number of school psychologists. Within the present study, researchers created the Graduate Enrollment Admissions Rating Scale (GEARS), a survey measuring several different factors that school psychology students consider when applying to graduate programs, to determine what factors contributed to school psychology students' choice of program.

Using Item Response Theory to Develop Revised (SSOSH-7) and Ultra-Brief (SSOSH-3) Self-Stigma of Seeking Help Scales.

The current research developed ultra-brief (SSOSH-3) and revised (SSOSH-7) versions of the Self-Stigma of Seeking Help scale. Item response theory was used to examine the amount of information each item provided across the latent variable scale and test whether items functioned differently across women and men. In a sample of 857 community adults, results supported removal of three reverse-scored items to create the SSOSH-7.

Development and evaluation of a new short form of the Conformity to Masculine Norms Inventory (CMNI-30).

The Conformity to Masculine Norms Inventory (CMNI) has been an important tool in researching masculinity. With the original measure at 94 items (Mahalik et al., 2003), there have been several abbreviated forms developed from 11 to 55 items.

Collegian help seeking: the role of self-compassion and self-coldness.

Background: Researchers have identified a two-factor structure of self-compassion (i.e. self-compassion and self-coldness).

A model of intention to provide mental health first aid in college students.

Background: Psychologically distressed college students' peers are often the first line of mental health support. Mental health first aid (MHFA) focuses on the quality of early intervention provided by peers to those in psychological distress but has neglected what motivates college students to provide MHFA.

Aims: The current study used the MHFA framework and bystander theory as a foundation to examine factors influencing college students' intention to provide MHFA.

Impact of integrated care and co-location of care on mental help-seeking perceptions.

Background: Integrated care may offer a solution to subpar mental health referral adherence, but people's openness to receiving psychological treatment in this setting is understudied.

Aims: The present study examined the influence of the integrated care context and co-location of care on people's help-seeking perceptions.

Method: This study ( = 397) used an experimental vignette design to compare the impact of treatment type (integrated care vs.

Physician referral to a psychologist: Testing alternative behavioral healthcare seeking models.

Objective: Primary care physicians (PCPs) often refer patients to psychological services, but help-seeking factors in the context of behavioral healthcare referral are understudied. This study examined perceptions of seeking psychological help for depression by comparing alternative structural equation models derived from the Theory of Reasoned Action (TRA).

Method: Internet survey participants (N = 685 US adults, 77% female, M  = 45) imagined themselves in a vignette scenario in which they are experiencing depression symptoms and encouraged by a PCP to see a psychologist.

Dimensionality, reliability, and predictive evidence of validity for three help-seeking intention instruments: ISCI, GHSQ, and MHSIS.

People's intention to seek help from a mental health professional is thought to be the proximal cause of help-seeking behavior and thus is a dependent variable frequently measured by help-seeking researchers. Using a research design that accounted for actual future help-seeking behavior, the present study documented the dimensionality, internal consistency, and predictive evidence of validity of 3 intention instruments: the Intentions to Seek Counseling Inventory (ISCI), General Help Seeking Questionnaire (GHSQ), and Mental Help-Seeking Intention Scale (MHSIS). The sample was composed of 405 community-dwelling adults who self-identified as currently experiencing a mental health concern.

A Statewide Antibiotic Stewardship Collaborative to Improve the Diagnosis and Treatment of Urinary Tract and Skin and Soft Tissue Infections.

Background: Colorado hospitals participated in a statewide collaborative to improve the management of inpatient urinary tract infections (UTIs) and skin and soft tissue infections (SSTIs). We evaluated the effects of the intervention on diagnostic accuracy and antibiotic use.

Methods: The main collaborative outcomes were proportion of UTI diagnoses that met criteria for symptomatic UTI; exposure to fluoroquinolones (UTI only); duration of therapy (UTIs and SSTIs); and exposure to antibiotics with broad gram-negative activity (SSTIs only).

Mental health literacy as theory: current challenges and future directions.

Background: Mental health literacy (MHL) is one increasingly researched factor thought to influence mental health behaviors. Researchers have argued for expanding the definition of MHL to include additional constructs, but no consensus has yet been reached on what constructs should be included as part of MHL.

Aims: The purpose of this paper is to (i) elucidate how the expansion of the MHL construct has impeded the growth of MHL research and (ii) through the lens of construct and theory development, highlight how these challenges might be remedied.

Mental Help Seeking Attitudes Scale (MHSAS): Development, reliability, validity, and comparison with the ATSPPH-SF and IASMHS-PO.

Attitudes is a key help-seeking construct that influences treatment seeking behavior via intention to seek help, per the theory of planned behavior (TPB). This article presents the development and psychometric evaluation of the Mental Help Seeking Attitudes Scale (MHSAS), designed to measure respondents' overall evaluation (unfavorable vs. favorable) of their seeking help from a mental health professional.

Men's Mental Health Help-Seeking Behaviors: An Intersectional Analysis.

Men seek mental health treatment less often than women. The present study sought to elucidate identities and individual difference characteristics that are associated with enhanced or decreased mental health help-seeking in a large national sample of U.S.

Disentangling Gratitude: A Theoretical and Psychometric Examination of the Gratitude Resentment and Appreciation Test-Revised Short (GRAT-RS).

This study extended our theoretical and applied understanding of gratitude through a psychometric examination of the most popular multidimensional measure of gratitude, the Gratitude, Resentment, and Appreciation Test-Revised Short form (GRAT-RS). Namely, the dimensionality of the GRAT-RS, the model-based reliability of the GRAT-RS total score and 3 subscale scores, and the incremental evidence of validity for its latent factors were assessed. Dimensionality measures (e.

Further examination of the factor structure of the Male Role Norms Inventory-Short Form (MRNI-SF): Measurement considerations for women, men of color, and gay men.

Using multigroup structural equation modeling in a large sample of online-survey respondents (N = 6,744), the present study examined the reliability and dimensionality of the Male Role Norms Inventory-Short Form (MRNI-SF), a popular measurement of traditional masculinity ideology (TMI), and also tested measurement invariance between individuals that do and do not fit the White heterosexual male TMI reference group. Results indicated that (a) it is appropriate to model the MRNI-SF using either a bifactor or unidimensional model but not a second-order model, (b) the raw MRNI-SF total score is a suitable measure of the general TMI construct, (c) the raw self-reliance through mechanical skills and negativity toward sexual minorities subscale scores may be appropriate measures of their respective specific factors (akin to subscale factors), and (d) SEM or ipsatizing procedures should be used to model the 5 other specific factors, given the insufficient model-based reliability of their raw subscale scores. When comparing men to women, White men to Black and Asian men, and gay men to heterosexual men, the MRNI-SF demonstrated configural invariance and at least partial metric invariance (i.

Highly Aggressive Women in a Forensic Psychiatric Hospital.

In this study, we compared three groups of women admitted to a public forensic inpatient facility over the course of a two-year period. Detailed and systematic examination of social and psychiatric histories revealed that the group with the most persistent levels of aggression differed from the other two groups with respect to frequency of self-harming behavior, intellectual impairment, hypothyroidism, a childhood diagnosis of attention deficit-hyperactivity disorder (ADHD), and age of onset of psychiatric and behavioral symptoms. The high-aggression group also had the highest rate of childhood physical and sexual abuse, but the difference between that group and the two lower aggression groups did not achieve statistical significance.

Novel characterization of capsule x-ray drive at the National Ignition Facility.

Indirect drive experiments at the National Ignition Facility are designed to achieve fusion by imploding a fuel capsule with x rays from a laser-driven hohlraum. Previous experiments have been unable to determine whether a deficit in measured ablator implosion velocity relative to simulations is due to inadequate models of the hohlraum or ablator physics. ViewFactor experiments allow for the first time a direct measure of the x-ray drive from the capsule point of view.

Disentangling self-stigma: are mental illness and help-seeking self-stigmas different?

Two established but disparate lines of research exist: studies examining the self-stigma associated with mental illness and studies examining the self-stigma associated with seeking psychological help. Whereas some researchers have implicitly treated these 2 constructs as synonymous, others have made the argument that they are theoretically and empirically distinct. To help clarify this debate, we examined in the present investigation the overlap and uniqueness of the self-stigmas associated with mental illness and with seeking psychological help.

Cross-cultural validity of the Self-Stigma of Seeking Help (SSOSH) scale: examination across six nations.

Researchers have found that the stigma associated with seeking therapy--particularly self-stigma--can inhibit the use of psychological services. Yet, most of the research on self-stigma has been conducted in the United States. This is a considerable limitation, as the role of self-stigma in the help-seeking process may vary across cultural groups.

Is stigma internalized? The longitudinal impact of public stigma on self-stigma.

Stigma is considered an important barrier to seeking mental health services. Two types of stigma exist: public stigma and self-stigma. Theoretically, it has been argued that public stigma leads to the development of self-stigma.

Assessing the utility of the willingness/prototype model in predicting help-seeking decisions.

Prior research on professional psychological help-seeking behavior has operated on the assumption that the decision to seek help is based on intentional and reasoned processes. However, research on the dual-process prototype/willingness model (PWM; Gerrard, Gibbons, Houlihan, Stock, & Pomery, 2008) suggests health-related decisions may also involve social reaction processes that influence one's spontaneous willingness (rather than planned intention) to seek help, given conducive circumstances. The present study used structural equation modeling to evaluate the ability of these 2 information-processing pathways (i.
