This article provides background information and concrete examples to assist practitioners in the implementation of the American Psychological Association's Resolution on Appropriate Therapeutic Responses to Sexual Orientation. It provides some general information about psychosocial aspects of lesbian, gay, or bisexual identities. It examines the issues surrounding the assertion that sexual orientation can be changed and the implications for practice. Vignettes, based on actual case studies, are used to illustrate how practitioners might respond appropriately to clients who are struggling with issues surrounding their sexual orientation.

Felix, a Gay Latino man, presented with anxiety and panic attacks, which were addressed as symptoms of minority stress and self-stigma. The client's panic attacks were eliminated and anxiety was reduced by cognitive-behavioral therapy that targeted his concealment of his sexual orientation and that increased his active coping. By facing his fears of the negative impact of self-disclosure of his sexual orientation, Felix improved his mental health and relationships with others. A positive four-month follow-up interview is described.

Psychological and behavioral health policies are critical in the successful public health responses to the COVID-19 pandemic. Psychologists trained in policy and advocacy can lead efforts to integrate psychological science and mental health considerations into policy responses to the pandemic. The authors summarize existing opportunities and propose expanding training opportunities, including undergraduate and graduate coursework, seminars, online, one-time trainings, continuing education, and postdoctoral fellowships. Public Significance StatementBehavior change is key to controlling the COVID-19 pandemic. Psychological science must be included in policymaking in order to design effective and humane policies. The likelihood that psychological science is included is increased when psychologists are trained to translate science to policy and then to advocate for these policies. This article provides a detailed description of how to educate and train psychologists in public policy and advocacy across the professional lifespan. This training is accessible and scalable for a wide variety of academic institutions, associations, and individuals at different career stages. Policy training for the psychology workforce expands our society's access to essential expertise and enables psychologists to contribute fully to the public good.

A behavioral assay was developed based on differential tendency of a protozoan to attach to an agar gel containing the test substance. The heterotrophic marine dinoflagellate Crypthecodinium (Gyrodinium) cohnii responded negatively (less tendency to attach) to epinephrine at concentrations above 5 X 10(-15)M and to norepinephrine at concentrations above 5 X 10(-9)M. Response to choline as choline H2 citrate, choline bitartrate, and choline chloride was negative above 10(-7)M, but response to the choline analog carbachol was positve (greater tendency to attach) in the range 5 X 10(-6) to 5 X 10(-4)M. Other responses to neurochemicals at comparable concentrations were: dopa, betaine, and glycine--positive; L-glutamic acid, tryptophan, putrescine, and taurine--negative. Serotonin was inert, responses to tyrosine and gamma-aminobutyric acid were variable, and phenylalanine (6 X 10(-3)M) and 5-hydroxytryptophan (5 X 10(-4)M) were negative only at the highest concentrations tested.
