Session frequency and length are determined according to the person’s needs, the reason for seeking support and the evaluation of the process. Sources commonly mention about 30–60 minutes for individual sessions and weekly or every-two-weeks meetings; the framework specific to each person is clarified together in the initial evaluation.
How long does a therapy session last?
Session length varies with the approach and the setting. Sources give the following lengths for cognitive behavioral therapy (CBT), psychodynamic psychotherapy and counseling:
| Source | Way of working | Session length |
|---|---|---|
| Royal College of Psychiatrists | CBT | Normally 30–60 minutes |
| Royal College of Psychiatrists | Individual psychodynamic psychotherapy | Usually 50 minutes |
| NHS | Counseling | Usually 50–60 minutes |
These lengths are general information; the length for a given person is determined together in the initial evaluation.
How often are therapy sessions held?
According to the Royal College of Psychiatrists, CBT sessions take place weekly or every two weeks, and psychotherapy in general involves regular meetings at the same time and place every week or two weeks. The college also notes that individual psychodynamic psychotherapy sessions can be weekly or more often if needed. Which schedule suits a person is decided together, based on the person’s needs and the psychologist’s evaluation.
What determines session frequency and length?
The meeting schedule is set with the person’s needs, the reason for seeking support, life circumstances and the course of the process in mind. Holding sessions at regular intervals matters for the continuity of the process and for following up on the topics being addressed. The framework for frequency and for the process is worked out together according to the first session and later evaluations.
What is covered in the first session is described in What Is Covered in the First Session?, and how the process is planned in How Is the Process Planned After the First Session?.
What does research say about session frequency and the number of sessions?
Research findings are at the group level and do not offer a recommendation for any individual. A systematic review of 26 studies of routinely delivered therapies (Robinson et al.) reported that weekly therapy appears to accelerate the rate of improvement compared with less frequent schedules.
In a study of 200 adults with depression (Bruijniks et al.), two sessions per week were associated with a larger reduction in symptoms than one session per week, although the study has its own limitations. In a meta-regression of 176 studies on adult depression (Ciharova et al.), no relationship was found between the number of sessions and effect size, and the association with weekly frequency was no longer significant once study characteristics were controlled for.
Can the session schedule change during the process?
The framework is discussed together not only in the first session but also in later evaluations. For this reason, it is possible to talk the schedule over again when the person’s needs, circumstances or the course of the process change. According to the Royal College of Psychiatrists, the overall length of psychotherapy is in most cases agreed within about a month of starting; for details, see How Long Does Psychological Support Take?.
Common misconceptions about session frequency and length
- “There is one ideal frequency for everyone.” Sources mention weekly and every-two-weeks schedules; which one suits a person depends on their needs and on the evaluation.
- “Session length is the same in every approach.” Sources give lengths ranging from 30 to 60 minutes; the length can differ with the approach and the setting.
- “Once a schedule is set, it cannot change.” The framework is revisited in later evaluations, and the schedule can be talked over again when needs change.
Expert note
Clinical Psychologist Özgün Emre Yaylacı’s perspective draws on cognitive behavioral and psychodynamic psychotherapy theories. From this perspective, the meeting schedule is considered not only as a practical matter of calendar and length but together with the person’s needs, circumstances and the course of the process; regular meetings are important so that the topics being worked on can be followed up.
Session length and frequency are specific to each person and are determined together in the initial evaluation. The information in this article is general and does not replace an evaluation.

Frequently asked questions
How many minutes does a session last?
According to the sources, individual sessions last about 30–60 minutes (30–60 in CBT, 50 in psychodynamic psychotherapy, 50–60 in counseling). Length varies with the approach and the setting; the length for a given person is determined together in the initial evaluation.
Is meeting weekly mandatory?
Weekly or every-two-weeks meetings are common, and more frequent meetings may come up in some situations. The schedule is decided together, based on the person’s needs and the psychologist’s evaluation.
Does meeting less often slow progress?
A systematic review reported that weekly therapy appears to accelerate the rate of improvement compared with less frequent schedules. The suitable schedule still varies from person to person, and this finding is not an individual recommendation.
Are two sessions per week more helpful?
In a study of 200 adults with depression, two sessions per week were associated with a larger reduction in symptoms; in a large meta-regression this association lost significance once study characteristics were controlled for. This is not a recommendation.
Does benefit increase as the number of sessions increases?
In a meta-regression of 176 studies on adult depression, no relationship was found between the number of sessions and effect size. The process is considered together with the person’s needs and goals rather than the number of sessions alone.
