- This study reports the results from a Swedish randomized controlled trial of a standardized behavior management intervention. The intervention targeted students with externalizing behavior in a regular education setting. First- and second-grade students (N = 100) from 38 schools were randomly assigned to either the intervention or an active comparison group. Observer, teacher, and peer ratings were collected at pretest, posttest (6 months later), and follow-up (14 months after pretest). Significant intervention effects were found on student externalizing behavior and teacher behavior management at both posttest and follow-up. The intervention effect on student externalizing behavior was mediated by change in teacher behavior. Moderating effects of demographic and classroom variables were explored, as well as the social validity of the intervention. The results are discussed in relation to cost-effectiveness and feasibility of behavioral interventions in typical school settings.

- We present photometric and spectroscopic observations of a luminous Type IIP Supernova (SN) 2009kf discovered by the Pan-STARRS 1 (PS1) survey and also detected by the Galaxy Evolution Explorer. The SN shows a plateau in its optical and bolometric light curves, lasting approximately 70 days in the rest frame, with an absolute magnitude of M V = -18.4 mag. The P-Cygni profiles of hydrogen indicate expansion velocities of 9000 km s-1 at 61 days after discovery which is extremely high for a Type IIP SN. SN 2009kf is also remarkably bright in the near-ultraviolet (NUV) and shows a slow evolution 10-20 days after optical discovery. The NUV and optical luminosity at these epochs can be modeled with a blackbody with a hot effective temperature (T ~ 16,000 K) and a large radius (R ~ 1 × 1015 cm). The bright bolometric and NUV luminosity, the light curve peak and plateau duration, the high velocities, and temperatures suggest that 2009kf is a Type IIP SN powered by a larger than normal explosion energy. Recently discovered high-z SNe (0.7 < z < 2.3) have been assumed to be IIn SNe, with the bright UV luminosities due to the interaction of SN ejecta with a dense circumstellar medium. UV-bright SNe similar to SN 2009kf could also account for these high-z events, and its absolute magnitude M NUV = -21.5 ± 0.5 mag suggests such SNe could be discovered out to z ~ 2.5 in the PS1 survey.

- Objective: The current study evaluated the efficacy of an Internet-based parent-training program for children with conduct problems. Dose-response ratio and costs for the program were also considered. Method: Parents of 104 children (aged 3-12 years) were randomly allocated to either parent training or a waitlist control condition. Diagnostic assessment was conducted at baseline and parent ratings of child externalizing behaviors and parent strategies were completed before and after treatment and at 6-month follow-up. Results: At post-treatment assessment, children whose parent(s) had received the intervention showed a greater reduction in conduct problems compared to the waitlist children. Between group intent-to-treat effect sizes (Cohen's d) on the Eyberg Intensity and Problem scales were .42 and .72, respectively (study completers .66 and 1.08). In addition, parents in the intervention group reported less use of harsh and inconsistent discipline after the treatment, as well as more positive praise. Effects on behavior problems were maintained at 6-month follow-up. Conclusions: The results support the efficacy of parent training, administered through Internet, with outcomes comparable to many of the group-based parent training programs. The efficacy, low cost, and higher accessibility make this intervention a fitting part in a stepped-care model.

Clinical Significance of Parent Training for Children with Conduct Problems

Tidskriftsartikel (refereegranskat)abstract
- While there is a strong evidence base for behavioral parent training in the treatment ofchild conduct problems, the clinical impact is less well known. Meta-analyses report effect sizes in the medium range, but the common practice of reporting "small," "medium," and "large" effects can be misleading and difficult to understand for practitioners and clients. There is a need for more research addressing the clinical significance of behavioral parent training, which would help to bridge the gap between research and practice. In the first part of this report, a reanalysis in termsof clinical significance of two outcome studies published by the authors was conducted. In the second part, the results from the first part were compared to six outcome studies published by other authors. The median number needed to treat across studies was five, which means that forevery five treated children, one shows reliable change and moves from the dysfunctional to the functional population.

When Cheap is Good : Cost-Effective Parent and Teacher Interventions for Children with Externalizing Behavior Problems
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is strong empirical support for behavioral parent training (BPT) as an intervention for children with externalizing behavior problems (EBP). However, there is a lack of studies that have investigated the effectiveness of BPT in routine care. Furthermore, most families in need of service do not gain access to it. Another issue of concern is that a sizable portion of children who take part in BPT does not show clinical significant improvement. With regard to behavioral teacher training (BTT) for students with EBP, there is a paucity of intervention trials using randomized design. The training procedures have rarely been standardized, which have resulted in interventions that are dependent upon heavy involvement of external consultants. To improve the accessibility to service for students with EBP, intervention models that are feasible for typical school personnel need to be developed. Study I investigated the effects of BPT in routine care. The participants were randomized to BPT with full practitioner support (BPT-P), self-administered BPT with minimal practitioner support (BPT-S), or a waitlist control group (WL). The study showed that BPT implemented by briefly trained social service employees (BPT-P) resulted in at least as large effects as previous efficacy studies. PMT-S also showed significant effects compared to the WL, but was less effective than PMT-P. Improvements in child behaviors were mediated by improved parenting behaviors. Study II investigated the effects of an enhanced version of the BPT-program from study I. The program targeted families with risk factors for non-response that were referred to service within the social services. The results showed strong intervention effects on child EBP and parent anxiety/depression for enhanced BPT compared to regular BPT. Study III used a randomized design to evaluate the effects of a standardized and feasible BTT program. At both posttest and follow-up, significant effects favoring the BTT-group over the active control group were found on student EBP, teacher behavior management, and peer problems. The study also showed that the effect on student EBP was mediated by change in teacher behavior management.

GALEX and Pan-STARRS1 Discovery of SN IIP 2010aq : The First Few Days After Shock Breakout in a Red Supergiant Star

Tidskriftsartikel (refereegranskat)abstract
- We present the early UV and optical light curve of Type IIP supernova (SN) 2010aq at z = 0.0862, and compare it to analytical models for thermal emission following SN shock breakout in a red supergiant star. SN 2010aq was discovered in joint monitoring between the Galaxy Evolution Explorer (GALEX) Time Domain Survey (TDS) in the NUV and the Pan-STARRS1 Medium Deep Survey (PS1 MDS) in the g, r, i, and z bands. The GALEX and Pan-STARRS1 observations detect the SN less than 1 day after the shock breakout, measure a diluted blackbody temperature of 31, 000 ± 6000 K 1 day later, and follow the rise in the UV/optical light curve over the next 2 days caused by the expansion and cooling of the SN ejecta. The high signal-to-noise ratio of the simultaneous UV and optical photometry allows us to fit for a progenitor star radius of 700 ± 200R sun, the size of a red supergiant star. An excess in UV emission two weeks after shock breakout compared with SNe well fitted by model atmosphere-code synthetic spectra with solar metallicity is best explained by suppressed line blanketing due to a lower metallicity progenitor star in SN 2010aq. Continued monitoring of PS1 MDS fields by the GALEX TDS will increase the sample of early UV detections of Type II SNe by an order of magnitude and probe the diversity of SN progenitor star properties.

Tidskriftsartikel (refereegranskat)abstract
- This study examined the effectiveness of a Swedish parent management training (PMT) intervention for parents of children aged 3 to 10 within the context of regular social service. Self-referred parents of 159 children (aged 3–10) with conduct problems were randomly assigned to either eleven practitioner-assisted group sessions (PMT-P), or a single instructional workshop followed by self-administration of the training material (PMT-S), or a waitlist control group. Intent-to-treat analyses showed that both PMT-P and PMT-S improved parent competence and reduced child conduct problems compared to the waitlist at posttest. Both training conditions showed further significant improvements at the 6-month follow-up. In direct comparison, PMT-P was superior to PMT-S on measures of child conduct problems at both posttest and follow-up. Improvement in child conduct was mediated by improvement in parent competencies and homework fidelity. The findings in this study have implications for large-scale dissemination of parent management training through different means of delivery.
