    Internet-based cognitive behavior therapy (ICBT) and self-help books have proven to be effective treatments for social anxiety. These treatments can increase the opportunity for more people to access evidence-based psychological treatment. More knowledge of the factors that predict treatment outcomes is needed for individuals to get the right type of treatment. The purpose of this study was to investigate if education level, recruitment mechanism, or previous psychological or psychopharmacological treatment predicts successful treatment outcomes in conjunction with self-help treatment for social anxiety disorder (with or without elements of ICBT). Two treatment groups (n = 138) underwent a six-week self-help treatment. Treatment for one of the groups included a mobile application. Measurements using the Liebowitz So-cial Anxiety Scale Self-Report as the main outcome measure were taken before, during, and in connection with the completion of treatment. Recruitment via DN was associated with higher odds of a successful treatment outcome (OR = 4.1) compared to recruitment via Facebook. Similarly, absence of previous psychological treatment was associated with higher odds of a successful treatment outcome (OR = 4.4).

    The human brain is supposed to have a capacity for supramodal evaluation of information-interaction from several senses (often studied through fMRI). Gunnar Borg’s Range Model is a theoretical framework for interindividual, intermodal and interdisciplinary comparisons. The model postulates that the total natural subjective dynamic range from zero (or the threshold) to maximum (or a terminal level very close to the maximal intensity) is approximately subjectively equal for all individuals. Each individual experience is thus interpreted in relation to its position in the individual range, regardless of the size of the physical stimulus range. For interindividual and intermodal comparisons it is also important to have a good reference, a firmly schematized conception, with high interindividual agreement. A maximal perceived exertion has been found to work well for this purpose. Perceived exertion is an emergent modality consisting of many symptoms and cues with several sensory systems involved in conveying information to the brain from the muscles, respiration, skin, joints etc.; and with several important physiological correlates (e.g., heart rate, blood lactate, ventilation, skin temperature). In contrast to many other modalities, the perception of exertion comes from an active interaction of the body with the environment and the person usually regulates performance as a response to the perception. For healthy people it is also not harmful with a maximal exertion.  Thus, a maximal perceived exertion is something most of us have experienced. In a questionnaire study the idea was investigated that, at least in some cases, what schematized conception is used will have importance. This should for example be true for modalities where individual experiences vary greatly, as, e.g., for pain. Modalities included were taste (sourness and sweetness), heaviness, loudness, brightness, fear, smell, and pain. Two groups of 20 persons (10 men and 10 women) followed one of two instructions. Group A compared each item with their conception of a maximal heaviness (as “100”) and Group B used item-specific (intramodal) references of "sourest, sweetest, loudest, etc., imaginable". The cross-modal task of comparing different modalities to the conception of a maximal heaviness worked well. As expected there was a significant difference between the two kinds of instructions for pain (with a lower mean value for group B, p < 0,001), but, and more importantly, also a larger variance for group B. For most modalities, except for pain, the intramodal references (sourest, sweetest, loudest, etc.) may thus be conceived of as similar across individuals as well as approximately equal to the reference of a maximal heaviness, or at least was used that way. For a modality, such as pain, where individual experiences may differ extensively, the cross-modal task of using the conception of a maximal heaviness should be preferred.

    In many sports, such as for example, in diving, figure skating and ski jumping, subjective assessment is essential in evaluating the performance. Judges usually score the performance according to a complicated setup of rules but uses quite simple rating scales. The Borg CR Scales®, commonly used for perceptual scaling of a variety of modalities and symptoms, may also be used for performance evaluation. The Borg CR100 Scale®, is a general intensity scale from 0 to 100,  "Maximal". For diving, “Maximal” was anchored in a "perfect dive". Five judges used the Borg CR100 scale together with the traditional scale for 4 men and 6 women who partook in the semi-finals in the Swedish Championships in diving, 2012. Judges were consistent in their way of using the scales, as can be seen from individual correlations with the contest results. Strong significant correlations were obtained between the traditional scale and the Borg CR100 scale® (r = 0.80) and for both scales with the contest results (0.63 and 0.62). With the Borg CR100 scale® several dives were assessed with a more precise differentiation between the dives. This is illustrated in Fig. 1 by the two individual dives no. 281 and 350. Since the CR100 is more finely graded, the scale gives a better flexibility in the judgments. Because the Borg CR scales can be used for self appraisal of for example perceived exertion, perceived difficulty, and motivation, the results in this study opens up an interesting field of possible comparisons in the study of performance enhancement and in the training of elite athletes.

    The Borg CR Scales® are general intensity scales suitable for most kinds of experiences and symptoms including loudness, but have predominantly been used for perceived exertion and pain assessment. Even if earlier versions have, the present Borg CR100 scale® has not, however, been tested on loudness. The scales are constructed to give ratio data and exponents that mimic what is obtained with magnitude estimation (ME). To also give level determinations and for interindividual comparisons, verbal labels are placed on the scale in congruence with the ratio scale from 0 (nothing at all) to 100 (”Maximal” and anchored in a previously experienced perception of, for example, perceived exertion), with, for example, ”Strong” at 50 and with the possibility to exceed 100 in extreme situations1. 36 university students (9 men and 27 women: mean age 22.4 years, s = 3.1 years) partook in a loudness experiment, scaling loudness with the Borg CR100 Scale®. All sounds, S ={40; 50; 60; 70; 80; 90; 100} dB(A), were presented four times in the same randomized order to all subjects. Sounds were generated by NMATLAB script, presented through earphones (Sennheiser HD 580 Precision) in a sound proof listening room using a stationary computer (Windows 7 Professional with RME Fireface 400 external sound card, sampling frequency 48 kHz, 24 bit depth). Geometric means of results obtained with the Borg CR100 scale® were R = {4.7; 7.3; 12.2; 19.2; 29.5; 51.0; 86.5} thus ranging from approx. “Very week” to just below “Extremely strong”. The power function, computed from individual geometric means, was R = 61.7 x S0.42 (r = 0.912) and thus similar to what has often been obtained with ME and also with previous versions of Borg CR scales. Coefficients of variation fell from 0.61 (40 dB) to 0.14 (100 dB), similar to what has been obtained for perceived exertion. The latest Borg CR100 scale® thus works fine for scaling loudness of pure tones.

    There are many demands on a good pain-scale. It should be possible to: use for all kinds of pain; determine direct levels of intensity over the total range; treat responses with statistical methods, preferably parametric statistics; study degrees of changes with stimulus intensity, medication and time; make interindividual, intermodal and psychophysiological comparisons; avoid ceiling and floor effects; make estimations and also productions; determine psychophysical S-R-functions, possible to describe with a general equations as, e.g., R=a+c(S-b)^n, where a is the basic “noise” at rest  (or the absolute threshold), and b is the starting point of the function; make two-way communication; handle round off tendencies; use internationally. To meet these demands the scale must be constructed according to basic psychophysical and linguistic knowledge, and tested in relevant experiments. To cover the total subjective range there is a need of a number variation from 0 to 50 or a little more, about 26. Several anchors should be used that people understand very well, and that are placed correctly. Most existing scales do not fulfill these demands. A common drawback is that there is a too limited range, or a maximal endpoint defined as “Highest (or Worst) Imaginable”, which is not a schematized conception and problematic for interindividual comparisons. Examples are the Visual Analogue Scale (VAS), and is the "Labeled Magnitude Scale" (LMS) for oral sensation. On the LMS verbal anchors are placed to give ratio data, but “Strong” is 34.7, “Very strong” 52,5. For general usage, e.g., in two-way communication for prescription of exercise, this is not good, nor does the scales facilitate predictions of max-levels from sub-max estimations. The best scales are the Borg CR Scales® (CR10 and CR100). In these scales quantitative semantics is used by applying ratio scaling to determine interpretation, meaning position in the range for congruence between anchors (labels) and numbers, and preciseness meaning interindividual agreement. It is especially important that the anchors for Zero and Maximal refer to schematized conceptions. A maximal magnitude is defined as a maximal perceived exertion and effort, for example a maximal heaviness. These ideas have been presented during several ISP meetings by G. Borg, last time in Freiburg 2013. The CR10 has been used in many studies, e.g., during tests of functional capacity and chest pain, and muscular-skeletal pain. The CR100 scale has, however, a greater potential as a general scale making possible determinations of most kinds of perceptual magnitudes. An advantage to the CR10 is that decimals need not be used and that the dynamic range is bigger and more in accordance with the psychophysical demands. The extra constants in the power function can then better reflect the true sensory processes.
