Tidsram
Change From Endpoint to Baseline in Connors's Adult ADHD Rating Scale-Investigator Rated: Screening Version - Japanese Version (CAARS-Inv:SV-J)
Tidsram: baseline and 8 weeks
Scale=30 items divided between 3 subscales: inattention (9 items), hyperactivity-impulsivity (9 items), and ADHD index (12 items), using a 4-point scale (0=not at all/never to 3=very much/very frequently). Total ADHD symptom score consisted of 18 items (sum of inattention and hyperactivity-impulsivity subscales) with range of scores from 0 to 54.
baseline and 8 weeks
Change From Endpoint to Baseline in Connors's Adult ADHD Rating Scale-Self Report: Screening Version - Japanese Version (CAARS-S:SV-J)
Tidsram: baseline and 8 weeks
Scale=30 items divided between 3 subscales: inattention (9 items), hyperactivity-impulsivity (9 items), and ADHD index (12 items), using a 4-point scale (0=not at all/never to 3=very much/very frequently). Total ADHD symptom score consisted of 18 items (sum of inattention and hyperactivity-impulsivity subscales) with range of scores from 0 to 54.
baseline and 8 weeks
Change From Endpoint to Baseline in Clinical Global Impression-ADHD - Severity
Tidsram: baseline and 8 weeks
Measures severity of the patient's overall severity of ADHD symptoms (1=normal, not at all ill; 7=among the most extremely ill patients).
baseline and 8 weeks
Change From Endpoint to Baseline in Hamilton Depression Rating Scale - 17 Items (HAMD-17) Total Score
Tidsram: baseline and 8 weeks
The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).
baseline and 8 weeks
Change From Endpoint to Baseline in Hamilton Anxiety Rating Scale - 14 Items (HAMA) Total Score
Tidsram: baseline and 8 weeks
The 14-item HAMA assesses the severity of anxiety. The investigator talked to the patient about their symptoms over the previous week before the study visit. Each item was scored using a 5-point scale, i.e. 0 = absent to 4 = severe. The total score of HAMA-14 may range from 0 (normal) to 56 (severe).
baseline and 8 weeks
Change From Endpoint to Baseline in 36-item Short-Form Health Survey (SF-36v2) Norm-based Subdomain and Summary Scores
Tidsram: baseline and 8 weeks

Derivation of norm-based scoring: Items re-scored to ensure choices were in consistent order and sum up converted score in each subscale; Transform subscale score; Normalize transformed subscale score (i.e. Z-score) using Japanese mean and standard deviation of SF-36v2 subscales.

Calculate: norm-based score=Z-score*10+50 in each subscale.
baseline and 8 weeks
Change From Endpoint to Baseline in Stroop Color Word Test
Tidsram: baseline and 8 weeks
An assessment of response inhibition. Three timed tests: reading color words in black ink; reading the printed colored ink; and reading color words printed in different colored ink. There were 100 items for each of the three test categories and if they made it through the 100 words with time remaining, they would repeat the list.
baseline and 8 weeks
Number of Participants With Potentially Clinically Significant Changes in Vital Signs During the Study
Tidsram: over 8 weeks
Vital signs reported are Pulse (beats per minute [bpm]), Systolic Blood Pressure (SBP) (mmHg), and Diastolic Blood Pressure (DBP) (mmHg).
over 8 weeks
Number of Participants With Potentially Clinically Significant Changes in Body Weight During the Study
Tidsram: over 8 weeks
Potentially clinically significant weight loss was defined as any decrease of at least 7%. Potentially clinically significant weight gain was defined as any increase of at least 7%.
over 8 weeks
Number of Participants With Abnormal QTc Interval Based on International Conference on Harmonisation Criterion
Tidsram: over 8 weeks
The Fridericia correction of the QT interval(QTcF) was used.
over 8 weeks
Cytochrome P450 2D6 (CYP2D6) Phenotype Status
Tidsram: 8 weeks
CYP2D6 is the primary atomoxetine metabolizing enzyme. Metabolizer status was determined by focusing on the normal, decreased, and defective allele. Poor metabolizer = defective/defective. Extensive metabolizer is all except for poor metabolizer.
