Editing Paradoxical intention (section)

=== Lack of reliable and objective research ===
Turner and Ascher say that paradoxical intention has not gained complete acceptance in behaviour therapy because the research supporting its clinical efficacy is mainly limited to uncontrolled case studies.<ref name=":3" />

Some have argued that studies have also shown a lack of evidence directly gleaned from the clients in order to explain the effectiveness of PI approaches, rendering the data unreliable, and that the insomniac self-reports are unreliable as participants may provide socially desirable answers.<ref>{{Cite journal|last=Riebel|first=Linda|date=1984|title=Paradoxical intention strategies: A review of rationales.|url=http://doi.apa.org/getdoi.cfm?doi=10.1037/h0085982|journal=Psychotherapy: Theory, Research, Practice, Training|language=en|volume=21|issue=2|pages=260–272|doi=10.1037/h0085982|issn=1939-1536}}</ref><ref>Carskadon, M.

Thereby, paradoxical intention is viewed as a last case resort in the event of the ineffectiveness of other relaxation-desensitisation programs.<ref name=":1" /><ref name=":0" />
