Exploring the construct validity of the Patient Perception Measure - Osteopathy (PPM-O) using classical test theory and Rasch analysis

What Makes an Osteopathic Treatment Effective From a Patient's Perspective: A Descriptive Phenomenological Study

OBJECTIVES

This study aimed to describe patients' perspectives on their experience in osteopathic treatment, to contribute toward developing interpretative models on effectiveness.

METHODS

A descriptive phenomenological approach was used. The data were collected through a semistructured interview. To capture the variability of the phenomenon, a purposive sample of 12 participants with previous experience of osteopathic care was selected. The data analysis was carried out in an inductive way, and it was parallel to the recruitment to continuously monitor the data saturation.

RESULTS

Data saturation was reached with 12 participants (female = 9; male = 3). Participants' age ranged from 27 to 82 years old (mean: 55.25 ± 17.15; median: 59; kurtosis: -0.82). Participants had different reasons for consultation. The analysis showed 1 overarching theme, "Osteopathy is a path of awareness," 3 themes, and 12 categories. Themes were: (1) "The experience of pain produces awareness of the need for care," (2) "Osteopathy is a journey to be shared over time," and (3) "The effectiveness of the osteopathic treatment is the discovery of the person's unity by experience."

CONCLUSION

Participants affirm that osteopathy is a path of awareness that starts from an experience of pain; leads them to contact an osteopath; and ends with their experience of the unity of body, mind, and spirit.

Evaluation of New Zealand osteopathy patients experiences of their treatment

OBJECTIVES

To investigate the experiences of patients seeking osteopathy treatment in New Zealand; and to describe their perceptions of osteopathic treatment.

DESIGN

Survey-based research design.

SETTING

Private osteopathy practices.

MAIN OUTCOME MEASURES

Demographic survey and the Patient Perception Measure-Osteopathy (PPM-O).

RESULTS

Twelve osteopaths were recruited as practitioners. Responses from 107 patients were analysed. Approximately 75% of patients reported receiving a 'mostly cranial' treatment approach. The majority of patients (96.2%) indicated that osteopathic treatment helped their condition. The most frequently experienced sensation was 'relaxed'. A positive relationship was observed between the PPM-O and demographic variables.

CONCLUSIONS

This is the first study to report on New Zealand osteopathy patient's experience of their treatment. The sensations and emotions experienced are largely consistent with previous Australian research. Predominantly positive perceptions of osteopathic treatment were reported. The current study provides some evidence of the construct validity of the PPM-O in a New Zealand patient population.
