An effective objective in psychiatric rehabilitation must be stated in terms that are both measurable and describe an observable behavior. Option B, "Arrive to work on time four out of five days per week," meets these criteria perfectly. The behavior, "arrive to work on time," is directly observable. The measure, "four out of five days per week," is specific, quantifiable, and allows for clear tracking of progress. This structure enables both the individual and the practitioner to objectively determine if the goal is being met. Such clarity is fundamental to the rehabilitation planning process, ensuring that goals are concrete and progress is demonstrable.

A. "Compliance" is an outcome or judgment rather than a directly observable behavior, and setting a 100% target can be unrealistic and counterproductive.

C. This statement is too vague. "Increase use" and "social skills" are not defined in specific, measurable, or observable terms.

D. "Learn" describes an internal cognitive process, not an observable behavior, and the term "more often" is not a specific, measurable quantity.

In Chapter 7, "The Skill and Resource Teaching and Learning Process," the authors emphasize that rehabilitation objectives must be stated in behavioral terms, specifying what the person will do, under what conditions, and at what level of proficiency (p. 165). Option B aligns with this principle.

2. Pratt, C. W., Gill, K. J., Barrett, N. M., & Roberts, M. M. (2014). Psychiatric Rehabilitation (3rd ed.). Academic Press. Chapter 10, "Developing a Rehabilitation Plan," discusses the importance of writing goals and objectives that are specific, measurable, achievable, relevant, and time-limited (SMART). It states that objectives should "describe behavior that can be observed and measured" (p. 215). Options C and D fail this test of specificity and measurability.

Boston University, Center for Psychiatric Rehabilitation. The handbook details the process of goal setting, stressing that objectives must be behaviorally specific and include criteria for success. An objective like "arrive to work on time" (behavior) "four out of five days" (criteria) is a classic example of a well-formed objective as described in the goal-setting sections.
