Primary Outcome Measures:
  • Self-rated sleep quality score measured by Insomnia Severity Index questionnaire [ Time Frame: Baseline, weekly during the treatment course, 1-week posttreatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Sleep parameters (sleep onset latency, sleep efficiency, total sleep time, times of wakening during sleep) by objective measure - wrist actigraphy [ Time Frame: Baseline, and 1-week posttreatment ] [ Designated as safety issue: No ]
  • Sleep parameters (sleep onset latency, sleep efficiency, total sleep time, times of wakening during sleep) by subjective measures using sleep log. [ Time Frame: Baseline, weekly during the treatment course, and 1-week posttreatment ] [ Designated as safety issue: No ]
  • Self-rated sleep quality score measured by the Pittsburgh Sleep Quality Index (PSQI) questionnaire [ Time Frame: Baseline, and 1-week posttreatment ] [ Designated as safety issue: No ]
  • Anxiety and depression states measured by Hospital Anxiety and Depression Scale (HADS) [ Time Frame: Baseline, and 1-week posttreatment ] [ Designated as safety issue: No ]
  • Subjects' functioning regarding work/study, social life and family measured by Sheehan Disability Index [ Time Frame: Baseline, and 1-week posttreatment ] [ Designated as safety issue: No ]
  • Subjects' credibility to the treatment measured by Credibility of treatment rating scale [ Time Frame: Second and the last time of the treatment ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Electroacupuncture

Acupoints will be treated at bilateral Ear Shenmen, Sishencong (EX-HN1), Anmian, and unilateral Yintang (EX-HN3) and Baihui (GV20).

Acupuncture will be performed by a registered Chinese medicine practitioner. "De qi"(an irradiating feeling considered to be indicative of effective needling) is achieved if possible. An electric-stimulator (CEFAR Acus II, Lund, Sweden) will be connected to these needles to give an electric-stimulation in continuous wave, frequency of 4 Hz, 0.45 ms square wave pulses and constant current. The needles will be left for 30 min and then removed. Acupuncture treatment will consist of three sessions per week for 3 consecutive weeks.

Other: Electroacupuncture
Acupuncture at bilateral Ear Shenmen, Sishencong EX-HN1, Anmian, and unilateral Yintang EX-HN3 and Baihui GV20. The needles will be left for 30 min and then removed. Acupuncture treatment will consist of three sessions per week for 3 consecutive weeks.
Other Name: Acupuncture
Placebo Comparator: Placebo Acupuncture
Placebo needles designed by Streitberger (1998) will be used. The placebo needles are blunt needle that will not penetrate the skin during needle insertion. The handles of these placebo needles will slide over the needle when it is compressed, giving it the appearance of penetrating the skin. The placebo needles are inserted to the same acupoints as stated in the electroacupuncture group. The needles are held by a surgical tape or hair pin in hairy region to imitate the retention of needles. The needles are connected to an electric-stimulator with zero frequency and amplitude. The number, duration and frequency of the treatment sessions, and the intervention procedure will be the same for electro-acupuncture and placebo acupuncture.

Detailed Description:

Acupuncture is potential to be an alternative treatment for primary insomnia. The purpose of this study is to evaluate the clinical effectiveness of acupuncture treatment on primary insomnia. This is a randomized single-blinded controlled trial. Patients will be randomly assigned to the electro-acupuncture group or the placebo acupuncture group. Patients will be put into groups and then compared.
