Level One Theraplay & MIM

About This Program

Target Population: Children ages 0-18 who exhibit behavioral problems and their caregiver (biological, adoptive, or foster)

For children/adolescents ages: 0 – 18

For parents/caregivers of children ages: 0 – 18

Program Overview

Level One Theraplay & MIM is a structured play therapy for children and their parents. Its goal is to enhance attachment, self-esteem, trust in others, and joyful engagement. The sessions are designed to be fun, physical, personal, and interactive and replicate the natural, healthy interactions between parents and young children. Children have been referred for a wide variety of problems including withdrawn or depressed behavior, overactive-aggressive behavior, temper tantrums, phobias, and difficulty socializing and making friends. Children also are referred for various behavior and interpersonal problems resulting from learning disabilities, developmental delays, and pervasive developmental disorders. Because of its focus on attachment and relationship development, Level One Theraplay & MIM has been used for many years with foster and adoptive families.

Essential Components

The essential components of Level One Theraplay & MIM include:

  • Session structure:
    • First session: Information-gathering interview with the parents.
    • Second and third sessions: Observation sessions using the Marschak Interaction Method (MIM), in which the child and one parent perform a series of interactive tasks together
      • The MIM is a structured technique for observing the relationship between two individuals.
      • It consists of a series of simple tasks designed to elicit a range of behaviors in the four Level One Theraplay dimensions:
        • Structure (key concepts: safety, organization, regulation)
        • Engagement (key concepts: connection, attunement, acceptance, expands positive affect)
        • Nurture (key concepts: regulation, secure base, worthiness)
        • Challenge (key concepts: competence, confidence, supports exploration)
      • The interactions are videotaped and later analyzed by the therapist(s) in preparation for a fourth session with the parents.
    • Fourth session: Planning session where the therapist(s) and parents discuss their observations of the interaction and together agree on a plan for treatment
    • Fifth through 20th session: Direct Level One Theraplay with the family
  • Treatment components:
    • Interactive and relationship-based which utilizes innate capacities for social interaction (rhythm, affective resonance and synchrony, and mirror neuron functions)
    • Provides a direct, here and now experience and utilizes now moments, non-congruence, and multiple foci of change
    • Guided by the adult and utilizes concepts of holding environment, authoritative parenting, and resilience building
    • Responsive, attuned, empathic, and reflective and utilizes contingency, primary intersubjectivity, attunement to vitality and categorical affects, empathy, mindfulness, and reflective function
    • Geared to the pre-verbal, social, right brain level of development and utilizes concepts of experience-dependent brain development, primacy of right brain development in early life, and co-regulation of physical and emotional internal states
    • Multisensory and utilizes touch and appropriate stimulation of body senses for social development, attachment, regulation of physiological development, stress reduction, and positive body image
    • Playful, but does not employ a lot of toys or props and utilizes affective synchrony and amplification of interest and joy to connect with the child
    • Involves parents in the treatment and strives to give parents a more positive, empathic view of their child, to have them become competent co-therapists, to teach them about appropriate developmental expectations, and to consult about behavior management
  • Typically provided as family therapy but has a group version available with a recommended group size of 4-10
  • There is also a group format for teacher-led school groups called Sunshine Circles that has not been reviewed by the CEBC.

Level One Theraplay & MIM has materials available in languages other than English:

Danish, Finnish, French, German, Italian, Japanese, Korean, Spanish, Swedish

For information on which materials are available in these languages, please check on the program's website or contact the program representative (contact information is listed at the bottom of this page).

Resources Needed to Run Program

The typical resources for implementing the program are:

Although Level One Theraplay & MIM may be conducted in any setting, ideally, an agency would have a treatment room of approximately 150 square feet (12 x 12) or so, with a small couch or love seat. A cabinet with doors for supplies or a tote bag is needed to contain materials and to keep distractions to a minimum. If the floor is hard or chilly, two 3 feet by 8 feet gym mats may be nice to have. Optimally, there would be very few other games/toys/furniture in order to reduce distraction. Optimally there would be an adjacent observation room with a one-way mirror to see the session; however, this is exceedingly rare in practice. A camera for recording the sessions and a computer or other mode to play back the videos is necessary. Video recording requires client's consent. It is possible, but not optimal, to practice the model without video recording.

Type of Study: Pretest–posttest study with a nonequivalent control group (Quasi-experimental)
Number of Participants: 189


  • Age — 2–6 years
  • Race/Ethnicity — German and Turkish
  • Gender — 64% Male and 36% Female
  • Status — Participants were children with language disorders, behavioral problems, and shyness/social anxiety referred from German and Australian medical centers.

Location/Institution: Germany and Australia

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to assess the efficacy of Theraplay [now called Level One Theraplay & MIM] for dually diagnosed children with language disorders and shyness/social anxiety. Participants were assigned in two waves to treatment conditions or a no-treatment control group. Measures utilized include the German version of the Clinical Assessment Scale for Child and Adolescent Psychopathology (CASCAP-D). Results indicate that children improved significantly on assertiveness, self-confidence, and trust. Social withdrawal was reduced. Expressive and receptive communication improved. Many behaviors normalized compared with neurologically healthy controls. Improvements were maintained over a 2-year period without relapse. Limitations include a lack of randomization, lack of generalizability due to ethnicity, and reliance on self-reported measures.

Length of controlled postintervention follow-up: 2 years (Wave 1 only).

Type of Study: One-group pretest-posttest
Number of Participants: 8


  • Age — 3–9 years (Mean=5.38 years)
  • Race/Ethnicity — Not specified
  • Gender — 6 Male and 2 Female
  • Status — Participants were children with mild to moderate autism.

Location/Institution: Not specified

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to evaluate Theraplay [now called Level One Theraplay & MIM] using a sample of autistic children. Measures utilized include the Marschak Interaction Method (MIM). Results indicate that both parents and children significantly improved across session according to the therapist evaluation. These findings suggest that as the intervention progressed, both children and parents became better at interacting during the therapy sessions. Significant changes were observed in the MIM interaction tasks. Overall, caregiver–child dyads scored significantly higher on the MIM interaction task from pretest to posttest. Further, dyads scored significantly higher on several specific dimensions. Limitations include a lack of randomization, lack of control group, small sample size, and lack of follow-up.

Length of controlled postintervention follow-up: None.

Type of Study: Randomized controlled trial
Number of Participants: 24 child-carer dyads


  • Age — Children: 2–6 years (average=8.2 years); Carers: Not specified
  • Race/Ethnicity — 100% Chinese
  • Gender — Children: 14 Male and 10 Female; Carers: 100% Female
  • Status — Participants were carers and children staying in foster care for various reasons relating to family and/or parenting issues.

Location/Institution: Six residential sites from one nongovernment organization

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to evaluate the effectiveness of two play-based programs in residential settings, a mixed-method study using randomized controlled trial, with the aims to enhance adult—child interaction and to reduce children’s behavior problems. Participants were randomly assigned to either Theraplay [now called Level One Theraplay & MIM] or board games. Measures utilized include the Strengths and Difficulties Questionnaire (SDQ) and the Parenting Relationship Questionnaire (PRQ). Results indicate that both programs were effective, and the attachment-based play program was shown to significantly reduce children’s emotional problems. Carers’ levels of sensitivity toward the children (on physical touch and intimacy) were indicated in the qualitative responses by the carers. Those carers in the board game group showed more understanding of the children and were able to observe them from a different perspective. Limitations include a small sample size, lack of generalizability due to ethnicity, use of a convenience sampling to recruit participants for the randomized study, the quality of the data may be affected by sampling bias, and reliance on self-reported measures.

Length of controlled postintervention follow-up: None.
