CNSL 688: Sex Therapy in Action: Assessment, Diagnosis, and Treatment of Psychosexual Issues and Dysfunction

A study guide to UMGC's clinical sex therapy elective on assessing, diagnosing and treating sexual concerns with a trauma-informed approach.

Updated October 2026 · 5 min read

CNSL 688 is UMGC's applied sex therapy course: it teaches how to assess, diagnose and treat sexual concerns, including those linked to trauma, health, relationships and environment.

It is a 3-credit elective in the M.S. in Clinical Professional Counseling. UMGC lists CNSL 606, 612, 627, 628 and CNSL 653 (or 685) as prerequisites, with CNSL 687 before or alongside it.

The course covers sexual dysfunctions, out-of-control sexual behavior and paraphilic disorders, the effects of sexual abuse, and referral and collaboration with other healthcare providers.

It is the most clinical of the three sexuality electives. Assignments expect accurate diagnostic reasoning, a clear rationale for the chosen model, and a plan that looks after the client's safety and wellbeing.

Key Concepts Explained

Diagnosing a Sexual Dysfunction

DSM-5-TR sexual dysfunctions include erectile disorder, female sexual interest/arousal disorder, female orgasmic disorder, delayed ejaculation, premature (early) ejaculation, genito-pelvic pain/penetration disorder, male hypoactive sexual desire disorder and substance/medication-induced sexual dysfunction.

Most require that the problem persists for about six months and causes significant distress, and that it is not better explained by another disorder, relationship distress, other stressors or a substance or medical condition.

Example: A client reports erection difficulties for three months since starting an SSRI. The duration is short and the timing points to medication, so a write-up would consider substance/medication-induced sexual dysfunction, recommend liaison with the prescriber, and avoid diagnosing erectile disorder at this stage.

Paraphilia Versus Paraphilic Disorder

The DSM-5-TR separates an unusual sexual interest (a paraphilia) from a paraphilic disorder, which requires distress or impairment, or acting on urges with a non-consenting person. Assignments test whether you can apply that distinction without stigma.

Treatment Models

Common approaches include the PLISSIT model (Permission, Limited Information, Specific Suggestions, Intensive Therapy), sensate focus exercises developed by Masters and Johnson, cognitive-behavioral work on anxiety and beliefs, and couples or systemic approaches. A strong plan explains why the model fits the client.

Ethics in Sex Therapy

Clinical work on sexuality requires clear boundaries, informed consent for any homework exercises, sensitivity to culture and religion, and practicing within competence. Case papers should state when a concern goes beyond your training and how you would refer.

Typical Assignments and How to Approach Them

Assignment typeWhat it testsHow to approach it
Diagnostic case write-upAccurate use of criteriaMatch each symptom to a criterion and state what you ruled out
Treatment planModel choice and goalsWrite measurable goals, interventions and a referral plan
Trauma-informed caseSafety and pacingPrioritize safety, choice and stabilization before sexual goals
Model comparison paperTheory knowledgeCompare fit, evidence and limits for one presenting concern

Running a Sexual Health Assessment

Case assignments often ask what you would assess before diagnosing. A thorough assessment usually covers the presenting concern in the client's own words, onset and duration, situations where the problem does and does not occur, medical history and medications, mental health, substance use, relationship context, trauma history (asked with care), cultural and religious values, and the client's goals.

Asking whether the problem happens in all situations or only some helps separate lifelong from acquired, and generalized from situational, presentations, which the DSM-5-TR specifiers require.
