title: Barriers and facilitators of access to psychological services for indigenous populations: A scoping review and thematic analysis

authors: Plessas, Anna

abstract: Background:
The extent to which behavior-analytic interventions are offered to Indigenous populations across CANZUS in accessible and culturally appropriate ways is unknown. We conducted a scoping review with a thematic analysis of the extant literature to find: (1) what are the barriers and facilitators for providing effective and equitable delivery of psychological services (with a behavioral component) to Indigenous populations; and (2) what tools and practices exist for an effective and equitable service delivery.
Methods:
We systematically reviewed Medline, CINAHL, PubMed, PsycInfo, Web of science, Ovid and INNZ databases between 1990 and 2020. For the scoping review, we adhered to the JBI methodological approach (2015) and the PRISMA strategy for the identification, selection, and appraisal of the reviewed articles. A total of 1265 unique articles met the criteria for the screening by title; 238 by abstract; 57 were included for full text assessment; and 37 were included in the final analysis.
Results:
Three themes were revealed to account for the barriers and facilitators of culturally friendly practices: (1) connecting practices are about interactions shaping the relationship between service provider and service client; (2) innovative practices test new approaches and innovations that could facilitate access to psychological services and overcome barriers, and (3) reflective practices are about critically examining the processes and actions undertaken toward effective cultural adaptation of services.
Conclusions:
Our analysis suggests that the level of success in bringing together services and the recipients of treatment (connection), showing flexibility and persistence in finding solutions (innovation) and examining the role of our behaviors in reaching our goals (reflection) is determined by the providers' action in the aforementioned three dimensions of practice.

title: Testing a suicidal ideation-to-action framework among Queer and Takatāpui people in Aotearoa New Zealand: An examination of the three-step theory

authors: Schimanski, Irie

abstract: The three-step theory (3ST) of suicide is well-established in the general population and shows promise for explaining suicidal ideation among Queer samples. This study examined the applicability of the 3ST using data from 250 Queer (n = 213) and Takatāpui (n = 37) people aged 18-74 living in Aotearoa New Zealand. The analytic approach entailed hierarchical multiple regression, ANOVA, t-tests, and logistic regression. Step-one was partially supported, with discrimination and hopelessness independently associated with suicidal ideation, but not their interaction. Step-two was fully supported, showing social support associated with lower suicidal ideation when social support exceeded discrimination, compared with the inverse. Full support for step-three was observed, finding higher self-harm among participants with histories of attempted suicide than those who had never attempted. An adapted version of the 3ST for Queer and Takatāpui people is presented, offering novel approaches to testing the ideation-to-action framework with these communities.

title: An Investigation of Catania's Concept of the Operant

authors: Cotton, Maree Louise

subjects: Response class

abstract: Catania (1973), in discussing the concept of the operant suggested responses should not be classified based on arbitrary criteria such as response function or topography alone, and rather should focus on the continuous distribution of responding. Catania (1973) hypothesised that response distributions would resemble a normal curve, even when reinforcement was provided for only those responses that occurred between two limits. Six domestic hens were used in a series of experiments in order to investigate Catania’s (1973) suggestion. In the first experiment the hens pecked at a flat screen with an infra-red device was mounted in front the screen to detect response location. Pecks in defined regions of the screen resulted in 3-s access to wheat. Over conditions, different quadrants of the screen were active. The whole screen remained white throughout each session except when the reinforcement was being delivered. The hens responded on a fixed-ration 5 schedule for 40 reinforcers per session. Over sessions the distribution of the locations of responses shifted to being centred over the active quadrant. Proportions of correct responses increased across sessions but incorrect responses persisted throughout. In Experiment 2 the screen was divided into ten 30-mm regions of which one was active in each condition while the whole screen remained white. The active region was moved in steps from the left to the right and from the right to the left of the screen over eleven conditions with eight sessions in each conditions and a fixed-ratio 5 schedule. In general, in each condition the proportion of correct responses increased to around 0.4. In each condition the distribution of response location shifted to being centred over the active region, resembling a normal distribution. In most cases, response rates on the active region were higher than for the inactive regions, hens usually responded on several regions at a moderate rate. In Condition 12 the active region was coloured red and this resulted in a narrower distribution of response locations, and higher proportions of correct response that other conditions for most hens. A large number of incorrect response persisted throughout this condition. These findings provide some evidence that supports Catania’s (1973) hypothetical response distributions. The argument is made that Catania’s (1973) concept of the operant could be a way to organise responses into a class and also that is provides a means of classifying response while maintaining the continuity of behaviour and, therefore, avoids the use of arbitrary criterion.
