Swedish project for the testing and assessment of the Comprehensive Stuttering Program (CSP) and the Speech Training Method Precision Fluency Shaping Program (PFSP)

The project "Computer-based Speech Training for People who Stutters" was organised by the Swedish Handicap Institute in collaboration with the Swedish Stammerers Association and was carried out in the period 1997-1999 financially supported by Allmänna Arvsfonden, the Swedish Ministry of Social Affairs

 

The Project comprised the translation and testing of the software program Dr. Fluency. At the same time, the speech training method Precision Fluency Shaping Program (PFSP) as a part of  the Comprehensive Stuttering Program (CSP) were introduced in Sweden. The Project represented a completely new view of stuttering. Unlike earlier, when stuttering was considered psychologically determined and where treatment such as the Non-Avoidance Therapy (NA) and psychotherapy were used, stuttering was now considered a physiologically determined disorder.

International research of the last 40 years and the WHO's definition substantiated the fact that stuttering is determined by physiological factors.

The Non-Avoidance Treatment has been unable to produce satisfactory results of outcome of therapy. 

 

The only therapy that fulfils the requirements on the results of stuttering treatment formulated by the research team Andrews et al. in 1983 are the following: Precision Fluency Shaping Program (PFSP) and Prolonged Speech.

 

The software program Dr. Fluency was translated and phonetically adapted to the Swedish language. Subsequently, ten persons representing varying degrees of stuttering disorders underwent an intensive speech training programme of 17 days. The individual training was conducted by the  computer in combination with speech and voice training transfer sessions in group or individually.

During the last days of treatment, the participants practised the overall objective of the treatment: normal, slow speech in different everyday situations.

 

Results

The participants were followed up for two years and the results were as indicated below:

After two years, five of the participants were assessed as no longer stuttering. The same persons stated in the questionnaire that they experienced increased communication proficiency and a feeling of enhanced self-confidence.

In other words, according to the final results, five of the eight persons that could be contacted two years after the project (i.e. 63%) have obtained very satisfactory results. They are content with the way they speak and communicate with other people.

By comparison, a Dutch survey (Franken, 1997) in which a group of especially selected stutterers of few mental problems assessed a similar treatment: 66% were satisfied with their speech pattern two years after the end of treatment.

R.L. Webster, who was the first to introduce the speech training method Precision Fluency Shaping Program (PFSP) at Hollins Communication Center in Virginia, USA, has the following report 10 months after the treatment: 70% of the participants state that the therapy has been very efficient. No one answered that they had had no effect at all; 4.5% indicated that the outcome was poor. The figures two years after the treatment are almost identical.

 

In the Swedish treatment programme, seven of eight persons (i.e. 88%) state that they are satisfied with the treatment two years after treatment.

 

The dropout rate over a two-year period is approx. 20% (2 persons) which is an acceptable figure (under 33%). Three of the remaining eight persons that did less well at the course inform that they are not satisfied with their own training effort. Two of them feel a need to receive follow-up treatment. This statement illustrates that they approve of the therapy and believe that the speech training may help them.

 

In comparison with the Non-Avoidance Therapy, this therapy can present considerably better results both in terms of fluency and reduced stuttering problem. PFSP should therefore be considered a worthy alternative to the Non-Avoidance Treatment programme offered by the public health authorities. The treatment Comprehensive Stuttering Program (CSP) including Precision Fluency Shaping Program (PFSP) is offered by Wästlunds Logopedmottagning, Prosodi in Örebro, Sweden.
